What makes 336 interesting

  • 336 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.
  • 336 is an abundant number: its proper factors sum to 656, which is 320 more than 336 itself.
  • 336 has 3 distinct prime factors (2, 3, 7), which is why it has so many divisors.

How to find the factors of 336 yourself

Divide 336 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 √33618.33, because every factor above that pairs with one below it.

336 ÷ 1 = 336
336 ÷ 2 = 168
336 ÷ 3 = 112
336 ÷ 4 = 84
336 ÷ 6 = 56
336 ÷ 7 = 48
336 ÷ 8 = 42
336 ÷ 12 = 28
336 ÷ 14 = 24
336 ÷ 16 = 21

Reading both columns gives every factor: 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336. The factor calculator does this automatically for any number.
