  • 1064 is a composite number, meaning it has more than two factors. It can be written as a product of smaller whole numbers in 8 different ways.
  • 1064 is an abundant number: its proper factors sum to 1336, which is 272 more than 1064 itself.
  • 1064 has 3 distinct prime factors (2, 7, 19), which is why it has so many divisors.

How to find the factors of 1064 yourself

Divide 1064 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 √106432.62, because every factor above that pairs with one below it.

1064 ÷ 1 = 1064
1064 ÷ 2 = 532
1064 ÷ 4 = 266
1064 ÷ 7 = 152
1064 ÷ 8 = 133
1064 ÷ 14 = 76
1064 ÷ 19 = 56
1064 ÷ 28 = 38

Reading both columns gives every factor: 1, 2, 4, 7, 8, 14, 19, 28, 38, 56, 76, 133, 152, 266, 532, 1064. The factor calculator does this automatically for any number.
