Lets's calculate LCM of 315,385

5 315, 385
7 63, 77
9, 11

∴ So the LCM of the given numbers is 5 x 7 x 9 x 11 = 3465

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3465

Therefore, the GCF of Fractions 647/315,7700/385 is 1/3465

Least Common Multiple of 315,385 with GCF Formula

Least Common Multiple of 315,385 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 315,385 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(315,385) = 35

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

GCF(315,385) x common factors =35 x 1 = 35

LCM(315,385) = ( 315 × 385 ) / 35

LCM(315,385) = 121275 / 35

LCM(315,385) = 3465
