Prime Factorization of 120

The number 120 is a composite number that consists of more than two factors. To find the prime factors or prime factorization of 120 some steps should be followed;

• Start with the number itself 120

• Then, let’s divide 120 by the smallest prime factor 2, 120 ÷ 2 = 60

• After that, continuing factorization of 60, 60 ÷ 2 = 30

• Then, Continue factoring the quotient 30, 30 ÷ 2 = 15

• Now, 15 can’t be divided by 2, so the next prime will be 3,15 ÷ 3 = 5

• At last, we get the prime number which is 5.

Therefore, prime factorization of 120 are 2 × 2 × 2 × 3 × 5 or 2³ × 3 × 5

Prime Factors of 120

As we have seen the prime factorization of 120 is given as;

120 = 2³ × 3 × 5

Hence, the Prime factor of 120 is 2 which is raised to power 3,3, and 5.

Factor Tree of 120

Here, the factor tree 120 is given below in the following steps;

• Start with 120

• Divide by the smallest prime factor, which is 2

• 2 is the prime number that remains as it is, 60 splits into two factors 2 and 30

• Then again, 2 will remain as it is, 30 splits into 2 and 15

• At last, 2 remain the same as above and 15 splits into two factors 3 and 5

Now you get the factors tree of 120, that is 2³ × 3 × 5

Factor tree of 120 is shown below:
