(number 438 has 8 factors)

Factor Pairs of 438

A Factor Pair of number 438 is a combination of two factors which can be multiplied together to equal 438.

List of all possible Factor Pairs of 438:

  • 1 × 438 = 438
  • 2 × 219 = 438
  • 3 × 146 = 438
  • 6 × 73 = 438

How to find the Factors of 438

Divide 438 by every whole number from 1 up to 20. Each division without a remainder gives a factor and its pair. There is no point going further: 21 × 21 = 441 is already greater than 438, so any larger divisor would pair with a smaller one you have already checked.

  • 438 ÷ 1 = 438 — factors 1 and 438
  • 438 ÷ 2 = 219 — factors 2 and 219
  • 438 ÷ 3 = 146 — factors 3 and 146
  • 438 ÷ 4 — remainder 2, not a factor
  • 438 ÷ 5 — remainder 3, not a factor
  • 438 ÷ 6 = 73 — factors 6 and 73
  • 438 ÷ 7 — remainder 4, not a factor
  • 438 ÷ 8 — remainder 6, not a factor
  • 438 ÷ 9 — remainder 6, not a factor
  • 438 ÷ 10 — remainder 8, not a factor
  • 438 ÷ 11 — remainder 9, not a factor
  • 438 ÷ 12 — remainder 6, not a factor
  • 438 ÷ 13 — remainder 9, not a factor
  • 438 ÷ 14 — remainder 4, not a factor
  • 438 ÷ 15 — remainder 3, not a factor
  • 438 ÷ 16 — remainder 6, not a factor
  • 438 ÷ 17 — remainder 13, not a factor
  • 438 ÷ 18 — remainder 6, not a factor
  • 438 ÷ 19 — remainder 1, not a factor
  • 438 ÷ 20 — remainder 18, not a factor

Why 438 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.

438 = 2 × 3 × 73

(1 + 1) × (1 + 1) × (1 + 1) = 8

Step-by-step factorization: Prime factors of 438.
