How to find the factors of 37
Test every whole number from 1 up to the square root of 37 (√37 ≈ 6.083). Each number that divides evenly gives you two factors at once: the divisor and the quotient.
- 37 ÷ 1 = 37 — so 1 and 37 are factors
- 37 ÷ 2 = 18.5 — not a whole number
- 37 ÷ 3 = 12.333 — not a whole number
- 37 ÷ 4 = 9.25 — not a whole number
- 37 ÷ 5 = 7.4 — not a whole number
- 37 ÷ 6 = 6.167 — not a whole number
Collecting both numbers from every successful division gives the complete list: 1 and 37.
