What is the Least Common Multiple of 6 and 418?

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 of 6 and 418 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 6 and 418, than apply into the LCM equation.

GCF(6,418) = 2
LCM(6,418) = ( 6 × 418) / 2
LCM(6,418) = 2508 / 2
LCM(6,418) = 1254

Least Common Multiple (LCM) of 6 and 418 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 6 and 418. First we will calculate the prime factors of 6 and 418.
