Least Common Multiple of 11 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 11 and 16, than apply into the LCM equation.

GCF(11,16) = 1
LCM(11,16) = ( 11 × 16) / 1
LCM(11,16) = 176 / 1
LCM(11,16) = 176

Least Common Multiple (LCM) of 11 and 16 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 11 and 16. First we will calculate the prime factors of 11 and 16.

Prime Factorization of 11

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

11 = 111

Prime Factorization of 16

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

16 = 24

Now multiplying the highest exponent prime factors to calculate the LCM of 11 and 16.

LCM(11,16) = 111 × 24
LCM(11,16) = 176
