What makes 112 interesting

  • 112 is a composite number, meaning it has more than two factors. It can be written as a product of smaller whole numbers in 5 different ways.
  • 112 is an abundant number: its proper factors sum to 136, which is 24 more than 112 itself.

How to find the factors of 112 yourself

Divide 112 by each whole number starting from 1. Whenever the division leaves no remainder, both the divisor and the quotient are factors. You only need to test up to √11210.58, because every factor above that pairs with one below it.

112 ÷ 1 = 112
112 ÷ 2 = 56
112 ÷ 4 = 28
112 ÷ 7 = 16
112 ÷ 8 = 14

Reading both columns gives every factor: 1, 2, 4, 7, 8, 14, 16, 28, 56, 112. The factor calculator does this automatically for any number.
