What is the Least Common Multiple of 99 and 104?

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 99 and 104 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 99 and 104, than apply into the LCM equation.

GCF(99,104) = 1
LCM(99,104) = ( 99 × 104) / 1
LCM(99,104) = 10296 / 1
LCM(99,104) = 10296

Least Common Multiple (LCM) of 99 and 104 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 99 and 104. First we will calculate the prime factors of 99 and 104.
