Lets's calculate LCM of 7938,3128

LCM of Fractions 7938/21,3128/404 is 12415032

2 7938, 3128
3969, 1564

∴ So the LCM of the given numbers is 2 x 3969 x 1564 = 12415032

Least Common Multiple of 7938,3128 with GCF Formula

Least Common Multiple of 7938,3128 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 7938,3128 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(7938,3128) = 2

common factors(in case of two or more numbers have common factors) = 1

GCF(7938,3128) x common factors =2 x 1 = 2

LCM(7938,3128) = ( 7938 × 3128 ) / 2

LCM(7938,3128) = 24830064 / 2

LCM(7938,3128) = 12415032


Lets's calculate GCF of 21,404

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 12415032/1

Therefore the LCM of Fractions 7938/21,3128/404 is 12415032
