What is the Least Common Multiple of 83 and 88?
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 83 and 88 is 7304.
LCM(83,88) = 7304
Least Common Multiple of 83 and 88 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 83 and 88, than apply into the LCM equation.
GCF(83,88) = 1
LCM(83,88) = ( 83 × 88) / 1
LCM(83,88) = 7304 / 1
LCM(83,88) = 7304
Least Common Multiple (LCM) of 83 and 88 with Primes
