What makes 560 interesting

  • 560 is a composite number, meaning it has more than two factors. It can be written as a product of smaller whole numbers in 10 different ways.
  • 560 is an abundant number: its proper factors sum to 928, which is 368 more than 560 itself.
  • 560 has 3 distinct prime factors (2, 5, 7), which is why it has so many divisors.

How to find the factors of 560 yourself

Divide 560 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 √56023.66, because every factor above that pairs with one below it.

560 ÷ 1 = 560
560 ÷ 2 = 280
560 ÷ 4 = 140
560 ÷ 5 = 112
560 ÷ 7 = 80
560 ÷ 8 = 70
560 ÷ 10 = 56
560 ÷ 14 = 40
560 ÷ 16 = 35
560 ÷ 20 = 28

Reading both columns gives every factor: 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560. The factor calculator does this automatically for any number.
