Write 420 as a product of its prime factor

Answers

Answered by GPT 3.5
To find the prime factorization of 420, we start by dividing it by the smallest prime number, which is 2.

420 ÷ 2 = 210

Since 210 is divisible by 2, we continue dividing:

210 ÷ 2 = 105

Again, we divide by 2:

105 ÷ 3 = 35

Now, we divide by 5:

35 ÷ 5 = 7

7 is a prime number, so we stop.

Therefore, the prime factorization of 420 is:

2 × 2 × 3 × 5 × 7

Written in multiplication form: 2^2 × 3 × 5 × 7
