What is the Least Common Multiple of 1031 and 1049?
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 1031 and 1049 is 1081519.
LCM(1031,1049) = 1081519
Least Common Multiple of 1031 and 1049 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 1049, than apply into the LCM equation.
GCF(1031,1049) = 1
LCM(1031,1049) = ( 1031 × 1049) / 1
LCM(1031,1049) = 1081519 / 1
LCM(1031,1049) = 1081519
Least Common Multiple (LCM) of 1031 and 1049 with Primes
