What is the Least Common Multiple of 22000 and 22006?

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 22000 and 22006 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 22000 and 22006, than apply into the LCM equation.

GCF(22000,22006) = 2
LCM(22000,22006) = ( 22000 × 22006) / 2
LCM(22000,22006) = 484132000 / 2
LCM(22000,22006) = 242066000

Least Common Multiple (LCM) of 22000 and 22006 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 22000 and 22006. First we will calculate the prime factors of 22000 and 22006.

Prime Factorization of 22000
