What makes 736 interesting

  • 736 is a composite number, meaning it has more than two factors. It can be written as a product of smaller whole numbers in 6 different ways.
  • 736 is an abundant number: its proper factors sum to 776, which is 40 more than 736 itself.

How to find the factors of 736 yourself

Divide 736 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 √73627.13, because every factor above that pairs with one below it.

736 ÷ 1 = 736
736 ÷ 2 = 368
736 ÷ 4 = 184
736 ÷ 8 = 92
736 ÷ 16 = 46
736 ÷ 23 = 32

Reading both columns gives every factor: 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736. The factor calculator does this automatically for any number.
