Least Common Multiple of 30 and 44 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 30 and 44, than apply into the LCM equation.

GCF(30,44) = 2
LCM(30,44) = ( 30 × 44) / 2
LCM(30,44) = 1320 / 2
LCM(30,44) = 660

Least Common Multiple (LCM) of 30 and 44 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 30 and 44. First we will calculate the prime factors of 30 and 44.

Prime Factorization of 30

Prime factors of 30 are 2, 3, 5. Prime factorization of 30 in exponential form is:

30 = 21 × 31 × 51

Prime Factorization of 44

Prime factors of 44 are 2, 11. Prime factorization of 44 in exponential form is:

44 = 22 × 111

Now multiplying the highest exponent prime factors to calculate the LCM of 30 and 44.

LCM(30,44) = 22 × 31 × 51 × 111
LCM(30,44) = 660
