GCF of Denominators means GCF of 980,128 as per the given fractions.

GCF of 980,128 is 4 as it is the largest common factor for these numbers.

Lets's calculate LCM of 657,6240

LCM of Fractions 657/980,6240/128 is 341640

3 657, 6240
219, 2080

∴ So the LCM of the given numbers is 3 x 219 x 2080 = 1366560

Least Common Multiple of 657,6240 with GCF Formula

Least Common Multiple of 657,6240 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 657,6240 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(657,6240) = 3

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

GCF(657,6240) x common factors =3 x 1 = 3

LCM(657,6240) = ( 657 × 6240 ) / 3

LCM(657,6240) = 4099680 / 3

LCM(657,6240) = 1366560


Lets's calculate GCF of 980,128

2 980, 128
2 490, 64
245, 32

∴ So the GCF of the given numbers is 2 x 2 = 4

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1366560/4

Therefore the LCM of Fractions 657/980,6240/128 is 341640
