Least Common Multiple of 4 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 4 and 26, than apply into the LCM equation.

GCF(4,26) = 2
LCM(4,26) = ( 4 × 26) / 2
LCM(4,26) = 104 / 2
LCM(4,26) = 52

Least Common Multiple (LCM) of 4 and 26 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 4 and 26. First we will calculate the prime factors of 4 and 26.

Prime Factorization of 4

Prime factors of 4 are 2. Prime factorization of 4 in exponential form is:

4 = 22

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 4 and 26.

LCM(4,26) = 22 × 131
LCM(4,26) = 52
