Factors of 494

How to find the factors of 494

Test every whole number from 1 up to the square root of 494 (√494 ≈ 22.226). Each number that divides evenly gives you two factors at once: the divisor and the quotient.

• 494 ÷ 1 = 494 — so 1 and 494 are factors
• 494 ÷ 2 = 247 — so 2 and 247 are factors
• 494 ÷ 3 = 164.667 — not a whole number
• 494 ÷ 4 = 123.5 — not a whole number
• 494 ÷ 5 = 98.8 — not a whole number
• 494 ÷ 6 = 82.333 — not a whole number
• 494 ÷ 7 = 70.571 — not a whole number
• 494 ÷ 8 = 61.75 — not a whole number
• 494 ÷ 9 = 54.889 — not a whole number
• 494 ÷ 10 = 49.4 — not a whole number
• 494 ÷ 11 = 44.909 — not a whole number
• 494 ÷ 12 = 41.167 — not a whole number
• 494 ÷ 13 = 38 — so 13 and 38 are factors
• 494 ÷ 14 = 35.286 — not a whole number
• 494 ÷ 15 = 32.933 — not a whole number
• 494 ÷ 16 = 30.875 — not a whole number
• 494 ÷ 17 = 29.059 — not a whole number
• 494 ÷ 18 = 27.444 — not a whole number
• 494 ÷ 19 = 26 — so 19 and 26 are factors
• 494 ÷ 20 = 24.7 — not a whole number
• 494 ÷ 21 = 23.524 — not a whole number
• 494 ÷ 22 = 22.455 — not a whole number

Collecting both numbers from every successful division gives the complete list: 1, 2, 13, 19, 26, 38, 247 and 494.

Prime factorization of 494

Divide by the smallest prime that fits, and keep going until the quotient is 1:

The primes you divided by give 494 = 2 × 13 × 19. From the exponents you can also count the factors without listing them: (1 + 1) × (1 + 1) × (1 + 1) = 8.

Properties of 494

• 494 is a composite number.
• The sum of all its factors is 840; the sum of its proper factors (excluding 494) is 346, which makes it a deficient number (its proper factors add up to less than itself).
• 494 is not a perfect square, so its factors pair up evenly.
• Multiples of 494 include 988, 1,482, 1,976, 2,470 and so on.
