Least Common Multiple of 10 and 26 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 26, than apply into the LCM equation.

GCF(10,26) = 2
LCM(10,26) = ( 10 × 26) / 2
LCM(10,26) = 260 / 2
LCM(10,26) = 130

Least Common Multiple (LCM) of 10 and 26 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 10 and 26. First we will calculate the prime factors of 10 and 26.

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 26

Prime factors of 26 are 2, 13. Prime factorization of 26 in exponential form is:

26 = 21 × 131

Now multiplying the highest exponent prime factors to calculate the LCM of 10 and 26.

LCM(10,26) = 21 × 51 × 131
LCM(10,26) = 130
