What are the Factors of 66?

Answer

Factors of 66:
1, 2, 3, 6, 11, 22, 33, 66

(number 66 has 8 factors)

Factor Pairs of 66

A Factor Pair of number 66 is a combination of two factors which can be multiplied together to equal 66.

List of all possible Factor Pairs of 66:

  • 1 × 66 = 66
  • 2 × 33 = 66
  • 3 × 22 = 66
  • 6 × 11 = 66

How to find the Factors of 66

Divide 66 by every whole number from 1 up to 8. Each division without a remainder gives a factor and its pair. There is no point going further: 9 × 9 = 81 is already greater than 66, so any larger divisor would pair with a smaller one you have already checked.

  • 66 ÷ 1 = 66 — factors 1 and 66
  • 66 ÷ 2 = 33 — factors 2 and 33
  • 66 ÷ 3 = 22 — factors 3 and 22
  • 66 ÷ 4 — remainder 2, not a factor
  • 66 ÷ 5 — remainder 1, not a factor
  • 66 ÷ 6 = 11 — factors 6 and 11
  • 66 ÷ 7 — remainder 3, not a factor
  • 66 ÷ 8 — remainder 2, not a factor

Why 66 has exactly 8 factors

The count follows from the prime factorization: add 1 to each exponent and multiply. Counting the divisors this way needs no trial division at all, however large the number is.

66 = 2 × 3 × 11

(1 + 1) × (1 + 1) × (1 + 1) = 8

Step-by-step factorization: Prime factors of 66.
