What's the Least Common Multiple (LCM) of 24, 36 and 50?

Answer

LCM of 24, 36 and 50 is
1,800

(One thousand eight hundred)

1,800 is the smallest positive integer that 24, 36 and 50 all divide without a remainder — every other common multiple of the three is a multiple of it.

Finding the LCM of 24, 36 and 50 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 24: 2 × 2 × 2 × 3 (exponent form: 23 × 3)

All Prime Factors of 36: 2 × 2 × 3 × 3 (exponent form: 22 × 32)

All Prime Factors of 50: 2 × 5 × 5 (exponent form: 2 × 52)

LCM = 23 × 32 × 52 = 1,800

Checking the LCM of 24, 36 and 50 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(24, 36) = (24 × 36) ÷ 12 = 864 ÷ 12 = 72

LCM(72, 50) = (72 × 50) ÷ 2 = 3,600 ÷ 2 = 1,800

LCM(24, 36, 50) = 1,800

The pairs may be taken in any order — 36 and 50 first, then 24 — and the answer is the same 1,800. That is exactly why the two routes on this page agree.
