What is the Least Common Multiple of 1006 and 1021?
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 1006 and 1021 is 1027126.
LCM(1006,1021) = 1027126
Least Common Multiple of 1006 and 1021 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 1006 and 1021, than apply into the LCM equation.
GCF(1006,1021) = 1
LCM(1006,1021) = ( 1006 × 1021) / 1
LCM(1006,1021) = 1027126 / 1
LCM(1006,1021) = 1027126
Least Common Multiple (LCM) of 1006 and 1021 with Primes
Least common multiple can be found by multiplying the highest exponent prime factors of 1006 and 1021. First we will calculate the prime factors of 1006 and 1021.
Prime Factorization of 1006
Prime factors of 1006 are 2, 503. Prime factorization of 1006 in exponential form is:
1006 = 21 × 5031
Prime Factorization of 1021
Prime factors of 1021 are 1021. Prime factorization of 1021 in exponential form is:
1021 = 10211
Now multiplying the highest exponent prime factors to calculate the LCM of 1006 and 1021.
LCM(1006,1021) = 21 × 5031 × 10211
LCM(1006,1021) = 1027126
