How to Find the Factors of 24 Using Division and Prime Factorization

The concept of factors of 24 plays a key role in mathematics and is widely applicable to both real-life situations and exam scenarios. Understanding the factors of a number helps students with topics like division, multiples, prime factorization, and solving real-world problems such as arranging groups or finding common divisors. Let’s learn all about the factors of 24 with Vedantu’s easy and clear explanation!


What Is Factors of 24?

A factor of 24 is any whole number that divides 24 exactly, leaving no remainder. In simple terms, if you can multiply two whole numbers together to get 24, then both those numbers are factors of 24. This concept is essential for understanding prime numbers, common multiples, and carrying out division in school maths and daily life situations.


List of All Factors and Factor Pairs of 24

The factors of 24 are the numbers you can evenly divide 24 by. Below is a complete list, including their positive and negative pairings:

Positive Factors Factor Pair
1 1 × 24
2 2 × 12
3 3 × 8
4 4 × 6
6 6 × 4
8 8 × 3
12 12 × 2
24 24 × 1

All positive factors: 1, 2, 3, 4, 6, 8, 12, and 24.
All negative factors: -1, -2, -3, -4, -6, -8, -12, and -24.


Prime Factorization of 24

Prime factorization is breaking down a composite number into a product of its prime numbers. Here are the steps to find the prime factors of 24:

1. Divide 24 by the smallest prime, 2: 24 ÷ 2 = 12

2. Divide 12 by 2: 12 ÷ 2 = 6

3. Divide 6 by 2: 6 ÷ 2 = 3

4. 3 is a prime number, so: 3 ÷ 3 = 1

So, the prime factorization of 24 is 2 × 2 × 2 × 3 or \( 2^3 \times 3^1 \).
Prime factors of 24: 2 and 3.


How to Find Factors of 24 (Step-by-Step Illustration)

  1. Start with 1 and 24: 1 × 24 = 24
  2. Test divisibility: 24 ÷ 2 = 12, so 2 and 12 are factors.
  3. Next, 24 ÷ 3 = 8, so 3 and 8 are factors.
  4. 24 ÷ 4 = 6, so 4 and 6 are factors.
  5. Try 5: 24 ÷ 5 = 4.8 (not a whole number) – not a factor.
  6. Continue up to √24 (~4.9), you get all unique pairs!

Key Formula for Number of Factors

To find the total number of factors, use the formula: If \( n = a^x \times b^y \), then number of factors = (x+1)(y+1). For 24: \( 2^3 \times 3^1 \) → (3+1) × (1+1) = 4 × 2 = 8 factors.


Relation to Other Numbers

Comparing factors of 24 with numbers like 18, 30, or 36 builds an understanding for LCM, HCF, and patterns in multiplication. See these for more examples: Factors of 36, Factors of 18, Factors of 30.


Real-Life Applications

Factors of 24 help with dividing objects equally (like sharing 24 chocolates among friends), arranging seats in groups, or in tiling, packaging, and planning events. Understanding factors supports logical thinking and problem-solving.


Speed Trick or Vedic Shortcut

A quick check: If an even number divides 24, or the individual digits of 24 (2+4=6) show divisibility by 3, use this in exams to spot factors without full division.

FAQs on Factors of 24 Explained with Complete Factor List

1. What are the factors of 24?

The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. These are the positive integers that divide 24 exactly without leaving a remainder.

  • 24 ÷ 1 = 24
  • 24 ÷ 2 = 12
  • 24 ÷ 3 = 8
  • 24 ÷ 4 = 6
  • 24 ÷ 6 = 4
  • 24 ÷ 8 = 3
  • 24 ÷ 12 = 2
  • 24 ÷ 24 = 1
All these numbers are called the positive factors or divisors of 24.

2. How do you find the factors of 24 step by step?

To find the factors of 24, divide 24 by whole numbers starting from 1 and check which divisions give no remainder.

  • Step 1: Start with 1 → 24 ÷ 1 = 24
  • Step 2: Check 2 → 24 ÷ 2 = 12
  • Step 3: Check 3 → 24 ÷ 3 = 8
  • Step 4: Check 4 → 24 ÷ 4 = 6
  • Continue up to 24
The numbers that divide 24 exactly are 1, 2, 3, 4, 6, 8, 12, 24.

3. What is the prime factorization of 24?

The prime factorization of 24 is 2 × 2 × 2 × 3 = 2³ × 3. This means 24 is written as a product of prime numbers only.

  • 24 ÷ 2 = 12
  • 12 ÷ 2 = 6
  • 6 ÷ 2 = 3
  • 3 ÷ 3 = 1
So the prime factors are 2 and 3.

4. How many factors does 24 have?

The number 24 has 8 positive factors. Using prime factorization 24 = 2³ × 3¹, we apply the formula:

  • Number of factors = (3 + 1)(1 + 1)
  • = 4 × 2
  • = 8
These factors are 1, 2, 3, 4, 6, 8, 12, and 24.

5. What are the factor pairs of 24?

The factor pairs of 24 are numbers that multiply together to give 24.

  • 1 × 24
  • 2 × 12
  • 3 × 8
  • 4 × 6
These pairs show how 24 can be written as a product of two whole numbers.

6. Is 24 a multiple of 6?

Yes, 24 is a multiple of 6 because 24 ÷ 6 = 4 with no remainder. A number is called a multiple of another number if it can be divided exactly without leaving a remainder. Since 6 × 4 = 24, 24 is a multiple of 6.

7. What are the common factors of 24 and 36?

The common factors of 24 and 36 are 1, 2, 3, 4, 6, and 12.

The numbers that appear in both lists are the common factors.

8. Is 24 a composite number?

Yes, 24 is a composite number because it has more than two factors. A composite number has factors other than 1 and itself. Since 24 has 8 factors (1, 2, 3, 4, 6, 8, 12, 24), it is not a prime number.

9. What is the greatest common factor (GCF) of 24 and 30?

The greatest common factor of 24 and 30 is 6.

  • Prime factorization of 24 = 2³ × 3
