What's the Least Common Multiple (LCM) of 35 and 40?

Answer

LCM of 35 and 40 is
280

First common multiples: 280, 560, 840, …

280 is divisible by both: 280 ÷ 35 = 8, 280 ÷ 40 = 7 — and 8 and 7 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/35 by 8 and of y/40 by 7.

35 = 5 × 7

40 = 23 × 5

— = power 0: the prime is not a factor of this number; the LCM takes it from the number that has it.

LCM = 23 × 5 × 7 = 280
