How To Find Factors of 57 Through Division Method?

The division method is one of the easy means of finding the factors of a number. As per this method, we will divide 57 with a sequence of integers. The numbers that divide 57 completely are known as their factors.

The steps below illustrate finding factors of 57 using the division method:


57 ÷ 1 = 57
57 ÷ 3 = 19
57 ÷ 19 = 3
57 ÷ 57 = 1


1, 3, 19, and 57 are the numbers that do not leave any remainder when divided by 57. So, the factors of 57 are 1, 3, 19, and 57.

What Is the Prime Factorization of 57?

Before using the prime factorization method, we must check if the given number is a prime number. If so, then it has only two factors: 1 and 57. If not, it has more than two factors.


57 is the composite number, with 4 factors in total. So, we can use prime factorization to find the factors of 57.


The steps to find prime factors of 57 using the prime factorization method are given below:


Step 1: Divide the number 57 by the smallest prime number that can divide it. The smallest prime number that can divide 57 is 3.
57 ÷ 3 = 19

Step 2: Now we should divide 19 by the next prime number. Since 19 itself is a prime number, it can be divided only by 19.9 ÷ 19 = 1


Since 1 (the quotient) cannot be divided further, the prime factors of 57 are 19 X 3.

What is the Factor Tree of 57?

We can also employ the factor tree method to find the factors of 57. According to this method, we will first place 57 on top of the factor tree. As part of its branches, we will write down one of the pair factors of 57. These factors will further be divided until all branches of the factor tree are prime numbers.


Step 1: We will place 57 at the top of the factor tree. We will branch it out to a pair of its factors, that is, 3 and 19

Step 2: 3 and 19 both happen to be prime numbers. The branches in the factor tree will now be all the prime numbers.


Hence, circling all the branches, 19 X 3= 57, which are 57 prime factors.
