How to Find All Factors and Prime Factors of Numbers 4–100
FAQs on Factoring Practice Worksheet: Numbers 4 to 100 for Class 4
1. What is factoring in math for Grade 4?
Factoring in Grade 4 math is the process of finding all the whole numbers that can be multiplied together to get a specific number. These numbers are called factors, and understanding them is a key part of building number sense and mastering basic arithmetic. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12.
2. How do you find all the factors of a number for Class 4?
To find all the factors of a number, you systematically check which numbers divide into it evenly, starting from 1. When you find a number that divides evenly, both that number and the result form a factor pair.
- Start with 1 and the number itself, as they are always factors.
- Check for divisibility by 2 (if it's even), then 3, 4, and so on.
- For example, for the number 36, the factor pairs are (1, 36), (2, 18), (3, 12), (4, 9), and (6, 6).
- The complete list of factors for 36 would be 1, 2, 3, 4, 6, 9, 12, 18, and 36.
3. What is a factor tree and how is it used in prime factorization for Class 4?
A factor tree is a special diagram used in a prime factorization worksheet for grade 4 to break down a number into its prime factors. You start with the main number and split it into a factor pair, creating two branches. You continue breaking down any composite numbers until you are only left with prime numbers at the end of the branches.
4. What is the difference between prime and composite numbers in this worksheet?
The main difference is that a prime number has exactly two factors (1 and itself), while a composite number has more than two factors. This worksheet helps you practise identifying both.
- Prime Numbers: Examples include 2, 3, 5, 7, and 11.
- Composite Numbers: Examples include 4, 6, 8, 9, and 10.
- The number 1 is a special case and is considered neither prime nor composite.
