Least Common Multiple of 12 and 29 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 12 and 29, than apply into the LCM equation.

GCF(12,29) = 1
LCM(12,29) = ( 12 × 29) / 1
LCM(12,29) = 348 / 1
LCM(12,29) = 348

Least Common Multiple (LCM) of 12 and 29 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 12 and 29. First we will calculate the prime factors of 12 and 29.

Prime Factorization of 12
