What is the Least Common Multiple of 351 and 368?
Least common multiple or lowest common denominator (lcd) can be calculated in two way; with the LCM formula calculation of greatest common factor (GCF), or multiplying the prime factors with the highest exponent factor.
Least common multiple (LCM) of 351 and 368 is 129168.
LCM(351,368) = 129168
Least Common Multiple of 351 and 368 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 351 and 368, than apply into the LCM equation.
GCF(351,368) = 1
LCM(351,368) = ( 351 × 368) / 1
LCM(351,368) = 129168 / 1
LCM(351,368) = 129168
Least Common Multiple (LCM) of 351 and 368 with Primes
