What is the Least Common Multiple of 1044 and 1055?

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 1044 and 1055 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 1044 and 1055, than apply into the LCM equation.

GCF(1044,1055) = 1
LCM(1044,1055) = ( 1044 × 1055) / 1
LCM(1044,1055) = 1101420 / 1
LCM(1044,1055) = 1101420
