Factors of 307

How to find the factors of 307

Test every whole number from 1 up to the square root of 307 (√307 ≈ 17.521). Each number that divides evenly gives you two factors at once: the divisor and the quotient.

• 307 ÷ 1 = 307 — so 1 and 307 are factors
• 307 ÷ 2 = 153.5 — not a whole number
• 307 ÷ 3 = 102.333 — not a whole number
• 307 ÷ 4 = 76.75 — not a whole number
• 307 ÷ 5 = 61.4 — not a whole number
• 307 ÷ 6 = 51.167 — not a whole number
• 307 ÷ 7 = 43.857 — not a whole number
• 307 ÷ 8 = 38.375 — not a whole number
• 307 ÷ 9 = 34.111 — not a whole number
• 307 ÷ 10 = 30.7 — not a whole number
• 307 ÷ 11 = 27.909 — not a whole number
• 307 ÷ 12 = 25.583 — not a whole number
• 307 ÷ 13 = 23.615 — not a whole number
• 307 ÷ 14 = 21.929 — not a whole number
• 307 ÷ 15 = 20.467 — not a whole number
• 307 ÷ 16 = 19.188 — not a whole number
• 307 ÷ 17 = 18.059 — not a whole number

Collecting both numbers from every successful division gives the complete list: 1 and 307.
