What is the Least Common Multiple of 12100 and 12116?
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 (LCM) of 12100 and 12116 is 36650900.
LCM(12100,12116) = 36650900
Least Common Multiple of 12100 and 12116 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 12100 and 12116, than apply into the LCM equation.
GCF(12100,12116) = 4
LCM(12100,12116) = ( 12100 × 12116) / 4
LCM(12100,12116) = 146603600 / 4
LCM(12100,12116) = 36650900
Least Common Multiple (LCM) of 12100 and 12116 with Primes
