What is the Least Common Multiple of 7005 and 7010?

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 7005 and 7010 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 7005 and 7010, than apply into the LCM equation.

GCF(7005,7010) = 5
LCM(7005,7010) = ( 7005 × 7010) / 5
LCM(7005,7010) = 49105050 / 5
LCM(7005,7010) = 9821010

Least Common Multiple (LCM) of 7005 and 7010 with Primes
