What is the Least Common Multiple of 300 and 304?

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 300 and 304 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 300 and 304, than apply into the LCM equation.

GCF(300,304) = 4
LCM(300,304) = ( 300 × 304) / 4
LCM(300,304) = 91200 / 4
LCM(300,304) = 22800

Least Common Multiple (LCM) of 300 and 304 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 300 and 304. First we will calculate the prime factors of 300 and 304.

Prime Factorization of 300
