Least Common Multiple of 48 and 64 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 48 and 64, than apply into the LCM equation.

GCF(48,64) = 16
LCM(48,64) = ( 48 × 64) / 16
LCM(48,64) = 3072 / 16
LCM(48,64) = 192

Least Common Multiple (LCM) of 48 and 64 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 48 and 64. First we will calculate the prime factors of 48 and 64.

Prime Factorization of 48

Prime factors of 48 are 2, 3. Prime factorization of 48 in exponential form is:

48 = 24 × 31

Prime Factorization of 64

Prime factors of 64 are 2. Prime factorization of 64 in exponential form is:

64 = 26

Now multiplying the highest exponent prime factors to calculate the LCM of 48 and 64.

LCM(48,64) = 26 × 31
LCM(48,64) = 192
