What is the Least Common Multiple of 82000 and 82004?

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 82000 and 82004 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 82000 and 82004, than apply into the LCM equation.

GCF(82000,82004) = 4
LCM(82000,82004) = ( 82000 × 82004) / 4
LCM(82000,82004) = 6724328000 / 4
LCM(82000,82004) = 1681082000

Least Common Multiple (LCM) of 82000 and 82004 with Primes
