What is the Least Common Multiple of 1039 and 1054?

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 1039 and 1054 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 1039 and 1054, than apply into the LCM equation.

GCF(1039,1054) = 1
LCM(1039,1054) = ( 1039 × 1054) / 1
LCM(1039,1054) = 1095106 / 1
LCM(1039,1054) = 1095106

Least Common Multiple (LCM) of 1039 and 1054 with Primes
