Factors of 72

Factors of 72 are numbers that divide 72 evenly, resulting in whole numbers without any remainder. Unlike prime numbers, which have only two factors (1 and the number itself), 72 is a composite number with multiple factors. When multiplying these factors in pairs, you get 72. Here are the factors of 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72.

Prime Factorization of 72

Prime factorization breaks down a number into its basic building blocks, the prime numbers. Here’s how 72 can be factorized:

  1. Divide 72 by the smallest prime number, which is 2: 72 ÷ 2 = 36
  2. Divide 36 by 2: 36 ÷ 2 = 18
  3. Divide 18 by 2: 18 ÷ 2 = 9
  4. Divide 9 by the next smallest prime number, which is 3: 9 ÷ 3 = 3
  5. Divide 3 by 3: 3 ÷ 3 = 1

So, the prime factorization of 72 is 2 × 2 × 2 × 3 × 3, or 23×32
