How to Calculate Factor Pairs of 72

Step-by-Step Process

To find all factor pairs of 72, we need to identify all integers that divide 72 evenly (with no remainder).

  1. Start with the smallest factor, which is always 1
  2. Check each integer from 1 up to the square root of 72 (v72 ≈ 8.49)
  3. For each factor found, its corresponding pair is calculated by dividing 72 by that factor

Calculation Example

Let's work through finding the factor pairs of 72:

Factor Check Division Result Factor Pair
72 ÷ 172.00Integer result(1, 72)
72 ÷ 236.00Integer result(2, 36)
72 ÷ 324.00Integer result(3, 24)
72 ÷ 418.00Integer result(4, 18)
72 ÷ 514.40Not a divisor-
72 ÷ 612.00Integer result(6, 12)
72 ÷ 710.29Not a divisor-
72 ÷ 89.00Integer result(8, 9)

More About Abundant Numbers

Abundant Numbers

An abundant number is a positive integer for which the sum of its proper divisors is greater than the number itself. The number 72 is abundant because the sum of its proper divisors (123) exceeds 72.

The smallest abundant number is 12, whose proper divisors are 1, 2, 3, 4, and 6, which sum to 16.
