What is the Least Common Multiple of 1013 and 1022?

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 1013 and 1022 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 1013 and 1022, than apply into the LCM equation.

GCF(1013,1022) = 1
LCM(1013,1022) = ( 1013 × 1022) / 1
LCM(1013,1022) = 1035286 / 1
LCM(1013,1022) = 1035286

Least Common Multiple (LCM) of 1013 and 1022 with Primes
