Answer

LCM of 43 and 52 is
2,236

First common multiples: 2,236; 4,472; 6,708; …

2,236 is divisible by both: 2,236 ÷ 43 = 52; 2,236 ÷ 52 = 43 — and 52 and 43 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/43 by 52 and of y/52 by 43.

43 and 52 are coprime (GCF = 1), so their LCM is simply the product: 43 × 52 = 2,236.
