Lets's calculate LCM of 75,93,640

3 75, 93, 640
5 25, 31, 640
5, 31, 128

∴ So the LCM of the given numbers is 3 x 5 x 5 x 31 x 128 = 297600

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/297600

Therefore, the GCF of Fractions 105/75,128/93,347/640 is 1/297600

Least Common Multiple of 75,93,640 with GCF Formula

Least Common Multiple of 75,93,640 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 75,93,640 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(75,93,640) = 1

common factors(in case of two or more numbers have common factors) = 15

GCF(75,93,640) x common factors =1 x 15 = 15

LCM(75,93,640) = ( 75 × 93 × 640 ) / 15

LCM(75,93,640) = 4464000 / 15

LCM(75,93,640) = 297600
