What's the Least Common Multiple (LCM) of 10, 25 and 35?

Answer

LCM of 10, 25 and 35 is
350

(Three hundred fifty)

350 is the smallest positive integer that 10, 25 and 35 all divide without a remainder — every other common multiple of the three is a multiple of it.

Finding the LCM of 10, 25 and 35 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 10: 2 × 5 (exponent form: 2 × 5)

All Prime Factors of 25: 5 × 5 (exponent form: 52)

All Prime Factors of 35: 5 × 7 (exponent form: 5 × 7)

LCM = 2 × 52 × 7 = 350

Checking the LCM of 10, 25 and 35 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(10, 25) = (10 × 25) ÷ 5 = 250 ÷ 5 = 50

LCM(50, 35) = (50 × 35) ÷ 5 = 1,750 ÷ 5 = 350

LCM(10, 25, 35) = 350

The pairs may be taken in any order — 25 and 35 first, then 10 — and the answer is the same 350. That is exactly why the two routes on this page agree.
