Factors of 68

What are the Factors of 68?

When you divide the number 68 and obtain a quotient which is a whole number, it is then known as a factor of 68. When the pairs are multiplied, the answer obtained is the original number. Once you have found out all the factors, they can be then arranged in ascending order. If you compare 68 with prime numbers, it is a composite number with two factors which are not prime numbers. Factors are not the same as multiples. To learn “what is the factor of 68?” the following questions must be answered:


What are the Factors of 68 and How to Find?

The answer to “What are the factors of 68?” is: All the numbers which are evenly divided by 68 are called factors of 68. First, we need to divide every number up to 68 to find out which one has an even quotient. When you do so, the following calculations show even quotient.


68 ÷ 1 = 68

68 ÷ 2 = 34

68 ÷ 4 = 17

68 ÷ 17 = 4

68 ÷ 34 = 2

68 ÷ 68 = 1

All the divisors above are used to divide and the factors of 68 are positive and get an even number. 


All factors of 68 are 1, 2, 4, 17, 34, and 68. 


Now, factors can include negative numbers as well. Therefore, the easiest way to find these numbers out is to convert the factors of 68 into negative numbers. The list is given below:

-1, -2, -4, -17, -34, and -68


Coming back to the question of “what is the factor of 68?” it is important to consider negative values as well. So, 68 has 6 factors in positive as well as negative.


Factor Pairs of 68

Factor pairs of 68 are just two factors that you have acquired when these factors are combined (multiplied) together, 68 is obtained. So what is the factor 68? Below are the positive factor pairs of 68:

1 × 68 = 68

2 × 34 = 68

4 × 17 = 68

17 × 4 = 68

34 × 2 = 68

68 × 1 = 68


As mentioned above, 68 can have negative factor numbers as well. By putting a minus in front of every factor will give you a positive 68 because of mimes into minus equals plus. Just like multiples, there can be negative factors to a number too.

-1 × -68 = 68

-2 × -34 = 68

-4 × -17 = 68

-17 × -4 = 68

-34 × -2 = 68

-68 × -1 = 68 


All Factors of 68 

Now that we have all factors of 68 present with us, when you arrange them in order, you get

68 > 34 > 17 > 4 > 1 

From this arrangement, you can understand that the smallest factor of 68 is 1 and the largest factor of 68 is 68.


The Prime Factorization of 68

So what is the prime factorization of 68? Firstly, there is no prime number of 68. Since 68 is a composite number, the prime factors can be obtained by


How to find the prime factorization of 68?

  1. First you have to divide 68 with the smallest prime factor which was 2 and the output which you get then has to again be divided by 2 till you land upon an odd number or a fraction. 

68 ÷ 2 = 34;

Divide 34 by 2.

34 ÷ 2 = 17

  1. We know that 17 is a prime number and the only two factors which it has is 1 and 17 so the calculation (division) cannot take place further.

  2. Therefore, the prime factorization of 68 can be written as 2 × 2 × 17 or 22 × 17, where 2 and 17 are the prime numbers.


What is the Factor of 68? Solved!

Therefore, from the above explanation, we know that 68 has only 6 positive as well as negative factors and when two negatives are multiplied a positive 68 is obtained. Moreover, 68 is not a prime number but a composite number because it has more than 1 factor. To learn about the factors of 68 one just has to keep dividing till we get an even quotient. Also, the prime factorization of 68 tells us how we can obtain 68 by multiplying the factors with each other. Various common factors of 68 can be derived when comparing with other numbers as well.


FAQ (Frequently Asked Questions)

1. What are the Factors for 68 and What is the Difference Between Factors and Multiples?

1, 2, 4, 17, 34, and 68 are the factors of 68. A lot of people get confused between factors and multiples of a given number. The factor of a number does not leave any remainder when it is divided by a second number. It is a number that can be multiplied to obtain another number. It is also finite. Whereas a multiple is a number found by multiplying a particular number with another number. Multiples are infinite. When a number is multiplied by an integer, multiples are obtained. The operation used in factors is division and multiples are multiplication.

2. What is a Factor of 68 and Why 68 is not a Prime Number?

In Mathematics, a prime number is a whole number that is always greater than 1. Prime numbers only have two factors which are 1 (a universal factor for every number) and the number itself. For example, number 68 has multiple factors that are more than 1. It has a total of 6 factors making it a complete composite number, where a composite is a positive integer. When two smaller positive integers are multiplied by each other a composite number is formed. In the same way, it has more than one divisor other than 1 and itself just like 68 does.
