What is the Least Common Multiple of 1047 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 (LCM) of 1047 and 1054 is 1103538.
LCM(1047,1054) = 1103538
Least Common Multiple of 1047 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 1047 and 1054, than apply into the LCM equation.
GCF(1047,1054) = 1
LCM(1047,1054) = ( 1047 × 1054) / 1
LCM(1047,1054) = 1103538 / 1
LCM(1047,1054) = 1103538
Least Common Multiple (LCM) of 1047 and 1054 with Primes
