What is the Least Common Multiple of 20600 and 20604?

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 20600 and 20604 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 20600 and 20604, than apply into the LCM equation.

GCF(20600,20604) = 4
LCM(20600,20604) = ( 20600 × 20604) / 4
LCM(20600,20604) = 424442400 / 4
LCM(20600,20604) = 106110600

Least Common Multiple (LCM) of 20600 and 20604 with Primes
