Least Common Multiple of 10001 and 10012 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 10001 and 10012, than apply into the LCM equation.

GCF(10001,10012) = 1
LCM(10001,10012) = ( 10001 × 10012) / 1
LCM(10001,10012) = 100130012 / 1
LCM(10001,10012) = 100130012

Least Common Multiple (LCM) of 10001 and 10012 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 10001 and 10012. First we will calculate the prime factors of 10001 and 10012.

Prime Factorization of 10001

Prime factors of 10001 are 73, 137. Prime factorization of 10001 in exponential form is:

10001 = 731 × 1371

Prime Factorization of 10012

Prime factors of 10012 are 2, 2503. Prime factorization of 10012 in exponential form is:

10012 = 22 × 25031

Now multiplying the highest exponent prime factors to calculate the LCM of 10001 and 10012.

LCM(10001,10012) = 731 × 1371 × 22 × 25031
LCM(10001,10012) = 100130012
