Least Common Multiple of 12 and 25 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 12 and 25, than apply into the LCM equation.

GCF(12,25) = 1
LCM(12,25) = ( 12 × 25) / 1
LCM(12,25) = 300 / 1
LCM(12,25) = 300

Least Common Multiple (LCM) of 12 and 25 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 12 and 25. First we will calculate the prime factors of 12 and 25.

Prime Factorization of 12

Prime factors of 12 are 2, 3. Prime factorization of 12 in exponential form is:

12 = 22 × 31

Prime Factorization of 25

Prime factors of 25 are 5. Prime factorization of 25 in exponential form is:

25 = 52

Now multiplying the highest exponent prime factors to calculate the LCM of 12 and 25.

LCM(12,25) = 22 × 31 × 52
LCM(12,25) = 300
