What are the Factors of 56?

The integers that divide 56 without leaving any remainder are known as the factors of 56.

 

For example, 4 is a factor of 56 because when we divide 56 by 4, it leaves 14 as the quotient and 0 as the remainder. Here, the quotient is also a factor of 56.

So, to check if the number is a factor of 56 or not, divide 56 by that number and verify whether the remainder is zero or not.

Factor List of 56

The factors of 56 are 1, 2, 4, 7, 8, 14, 28, and 56.

The Prime Factors of 56

The number 56 is a composite number, that is, it has more than two numbers as factors. To find the prime factors, first we will divide the number 56 by its smallest prime factor, that is, 2.

 

56 ÷ 2 = 28

 

Again, divide it by 2:

 

28 ÷ 2 = 14

 

14 ÷ 2 = 7

Now, divide by it the next prime numbers, that is, 3, 5, 7, and so on.

 

7 ÷ 3 = 2 and it leaves 1 as the remainder, which is not a factor.

 

7 ÷ 5 = 1 and it leaves 2 as the remainder, which is not a factor.

 

So, divide by the next prime number, that is, 7.

 

7 ÷ 7 = 1

 

So, the prime factorization of 56 = 2 × 2 × 2 × 7 or 2\( ^3 \) × 7.

 

This means that 2 and 7 are the prime factors of 56.

The Factor Pairs of 56

The factor pairs are two factors that, when multiplied together, give the original number as the result.

 

Example: (7, 8) is the factor pair of 56.

 

The factor pairs can be a positive pair or a negative pair.

The Positive Factor Pairs of 56

When two positive numbers are multiplied, the product is positive.

Solved Factors of 56 Examples

Example 1: Find the common factor of 53 and 56.

 

Solution:

 

The factors of 53 = 1 and 53

 

The factors of 56 = 1, 2, 4, 7, 8, 14, 28, and 56.

 

Therefore, the common factor of 53 and 56 is 1.

 

 

Example 2: Find the common factors of 56 and 28.

 

Solution:

 

The factors of 56 = 1, 2, 4, 7, 8, 14, 28, and 56.

 

The factors of 28 = 1, 2, 4, 7, 14, and 28.

 

Therefore, the common factors of 56 and 28 are 1, 2, 4, 7, 14, and 28.

 

 

Example 3: Archer decides to divide 56 marbles among 7 of her friends. How can she divide the marbles equally?

 

fac56

 

Solution:

 

56 ÷ 7 = 8

 

As 7 is a factor of 56, we get 0 as the remainder.

 

Therefore, to divide the marbles equally, Archer would have to give each of her 7 friends 8 marbles each.

Frequently Asked Questions on Factors of 56
