What is the Least Common Multiple of 91 and 108?
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 91 and 108 is 9828.
LCM(91,108) = 9828
Least Common Multiple of 91 and 108 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 91 and 108, than apply into the LCM equation.
GCF(91,108) = 1
LCM(91,108) = ( 91 × 108) / 1
LCM(91,108) = 9828 / 1
LCM(91,108) = 9828
Least Common Multiple (LCM) of 91 and 108 with Primes
