How to find the factors of 29

Test every whole number from 1 up to the square root of 29 (√29 ≈ 5.385). Each number that divides evenly gives you two factors at once: the divisor and the quotient.

  • 29 ÷ 1 = 29 — so 1 and 29 are factors
  • 29 ÷ 2 = 14.5 — not a whole number
  • 29 ÷ 3 = 9.667 — not a whole number
  • 29 ÷ 4 = 7.25 — not a whole number
  • 29 ÷ 5 = 5.8 — not a whole number

Collecting both numbers from every successful division gives the complete list: 1 and 29.
