## Least Common Multiple of 13 and 16 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 13 and 16, than apply into the LCM equation.

GCF(13,16) = 1
LCM(13,16) = ( 13 × 16) / 1
LCM(13,16) = 208 / 1
LCM(13,16) = 208

## Least Common Multiple (LCM) of 13 and 16 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 13 and 16. First we will calculate the prime factors of 13 and 16.

### Prime Factorization of 13

Prime factors of 13 are 13. Prime factorization of 13 in exponential form is:

13 = 131

### Prime Factorization of 16

Prime factors of 16 are 2. Prime factorization of 16 in exponential form is:
