What's the Least Common Multiple (LCM) of 25 and 36?

Answer

LCM of 25 and 36 is
900

First common multiples: 900; 1,800; 2,700; …

900 is divisible by both: 900 ÷ 25 = 36, 900 ÷ 36 = 25 — and 36 and 25 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/25 by 36 and of y/36 by 25.

25 and 36 are coprime (GCF = 1), so their LCM is simply the product: 25 × 36 = 900.

25 = 52

36 = 22 × 32

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

LCM = 22 × 32 × 52 = 900
