What is the Least Common Multiple of 10004 and 10019?

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 10004 and 10019 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 10004 and 10019, than apply into the LCM equation.

GCF(10004,10019) = 1
LCM(10004,10019) = ( 10004 × 10019) / 1
LCM(10004,10019) = 100230076 / 1
LCM(10004,10019) = 100230076

Least Common Multiple (LCM) of 10004 and 10019 with Primes
