What is the Least Common Multiple of 1031 and 1051?

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 1031 and 1051 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 1031 and 1051, than apply into the LCM equation.

GCF(1031,1051) = 1
LCM(1031,1051) = ( 1031 × 1051) / 1
LCM(1031,1051) = 1083581 / 1
LCM(1031,1051) = 1083581

Least Common Multiple (LCM) of 1031 and 1051 with Primes
