What's the Least Common Multiple (LCM) of 33 and 38?

Answer

LCM of 33 and 38 is
1,254

First common multiples: 1,254; 2,508; 3,762; …

1,254 is divisible by both: 1,254 ÷ 33 = 38; 1,254 ÷ 38 = 33 — and 38 and 33 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/33 by 38 and of y/38 by 33.

33 and 38 are coprime (GCF = 1), so their LCM is simply the product: 33 × 38 = 1,254.

33 = 3 × 11

38 = 2 × 19
