Least Common Multiple of 14 and 19 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 14 and 19, than apply into the LCM equation.

GCF(14,19) = 1
LCM(14,19) = ( 14 × 19) / 1
LCM(14,19) = 266 / 1
LCM(14,19) = 266

Least Common Multiple (LCM) of 14 and 19 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 14 and 19. First we will calculate the prime factors of 14 and 19.

Prime Factorization of 14

Prime factors of 14 are 2, 7. Prime factorization of 14 in exponential form is:

14 = 21 × 71

Prime Factorization of 19

Prime factors of 19 are 19. Prime factorization of 19 in exponential form is:

19 = 191

Now multiplying the highest exponent prime factors to calculate the LCM of 14 and 19.

LCM(14,19) = 21 × 71 × 191
LCM(14,19) = 266
