What's the Least Common Multiple (LCM) of 2, 14 and 32?

Answer

LCM of 2, 14 and 32 is

224

(Two hundred twenty-four)

224 is the smallest positive integer that 2, 14 and 32 all divide without a remainder — every other common multiple of the three is a multiple of it.

Finding the LCM of 2, 14 and 32 by Prime Factorization

Split all three numbers into prime factors, then take every prime that shows up in at least one of them, each raised to the highest power it reaches there. Multiplying those highest powers gives the least common multiple:

All Prime Factors of 2: 2 (exponent form: 2)

All Prime Factors of 14: 2 × 7 (exponent form: 2 × 7)

All Prime Factors of 32: 2 × 2 × 2 × 2 × 2 (exponent form: 2⁵)

Prime factor	2	14	32	Highest power
2	2	2	2⁵	2⁵
7	—	7	—	7

LCM = 2⁵ × 7 = 224

Checking the LCM of 2, 14 and 32 Two Numbers at a Time

The least common multiple is associative, so three numbers can be handled as two pairs: first the LCM of the first two, then the LCM of that value and the third. Each pair goes through the two-number formula, which uses the greatest common divisor:

LCM(a, b) = (a × b) ÷ GCD(a, b)

LCM(2, 14) = (2 × 14) ÷ 2 = 28 ÷ 2 = 14

LCM(14, 32) = (14 × 32) ÷ 2 = 448 ÷ 2 = 224

LCM(2, 14, 32) = 224

The pairs may be taken in any order — 14 and 32 first, then 2 — and the answer is the same 224. That is exactly why the two routes on this page agree.
