What is the Least Common Multiple of 1003 and 1010?
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 1003 and 1010 is 1013030.
LCM(1003,1010) = 1013030
Least Common Multiple of 1003 and 1010 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 1003 and 1010, than apply into the LCM equation.
GCF(1003,1010) = 1
LCM(1003,1010) = ( 1003 × 1010) / 1
LCM(1003,1010) = 1013030 / 1
LCM(1003,1010) = 1013030
Least Common Multiple (LCM) of 1003 and 1010 with Primes
Least common multiple can be found by multiplying the highest exponent prime factors of 1003 and 1010. First we will calculate the prime factors of 1003 and 1010.
