What is the Least Common Multiple of 10005 and 10022?

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 10005 and 10022 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 10005 and 10022, than apply into the LCM equation.

GCF(10005,10022) = 1
LCM(10005,10022) = ( 10005 × 10022) / 1
LCM(10005,10022) = 100270110 / 1
LCM(10005,10022) = 100270110

Least Common Multiple (LCM) of 10005 and 10022 with Primes
