What is the Least Common Multiple of 22100 and 22109?

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 22100 and 22109 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 22100 and 22109, than apply into the LCM equation.

GCF(22100,22109) = 1
LCM(22100,22109) = ( 22100 × 22109) / 1
LCM(22100,22109) = 488608900 / 1
LCM(22100,22109) = 488608900

Least Common Multiple (LCM) of 22100 and 22109 with Primes
