Least Common Multiple of 10 and 17

Least common multiple or lowest common denominator (lcd) can be calculated in two way; with the LCM formula calculation of greatest common factor (GCF), or multiplying the prime factors with the highest exponent factor.

Least common multiple (LCM) of 10 and 17 is 170.

LCM(10,17) = 170

Least Common Multiple of 10 and 17 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 10 and 17, than apply into the LCM equation.

GCF(10,17) = 1
LCM(10,17) = ( 10 × 17) / 1
LCM(10,17) = 170 / 1
LCM(10,17) = 170

Least Common Multiple (LCM) of 10 and 17 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 10 and 17. First we will calculate the prime factors of 10 and 17.

Prime Factorization of 10

Prime factors of 10 are 2, 5. Prime factorization of 10 in exponential form is:

10 = 21 × 51

Prime Factorization of 17

Prime factors of 17 are 17. Prime factorization of 17 in exponential form is:

17 = 171

Now multiplying the highest exponent prime factors to calculate the LCM of 10 and 17.

LCM(10,17) = 21 × 51 × 171
LCM(10,17) = 170
