What makes 512 interesting

  • 512 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.
  • 512 is a perfect cube: 8 × 8 × 8 = 512.
  • 512 is a deficient number: its proper factors sum to 511, which is 1 less than 512 itself.
  • 512 is a prime power: it is 2 raised to the power of 9. All of its factors are powers of 2.

How to find the factors of 512 yourself

Divide 512 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 √51222.63, because every factor above that pairs with one below it.

512 ÷ 1 = 512
512 ÷ 2 = 256
512 ÷ 4 = 128
512 ÷ 8 = 64
512 ÷ 16 = 32

Reading both columns gives every factor: 1, 2, 4, 8, 16, 32, 64, 128, 256, 512. The factor calculator does this automatically for any number.
