Lets's calculate LCM of 63,856

Given numbers has no common factors except 1. So, there LCM is their product i.e 53928

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 12/53928

Therefore, the GCF of Fractions 660/63,408/856 is 12/53928

Least Common Multiple of 63,856 with GCF Formula

Least Common Multiple of 63,856 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 63,856 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(63,856) = 1

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

GCF(63,856) x common factors =1 x 1 = 1

LCM(63,856) = ( 63 × 856 ) / 1

LCM(63,856) = 53928 / 1

LCM(63,856) = 53928
