So the greatest common factor 385,3990 is 35.

Lets's calculate LCM of 254,410

2 254, 410
127, 205

∴ So the LCM of the given numbers is 2 x 127 x 205 = 52070

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 35/52070

Therefore, the GCF of Fractions 385/254,3990/410 is 35/52070

Least Common Multiple of 254,410 with GCF Formula

Least Common Multiple of 254,410 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 254,410 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(254,410) = 2

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

GCF(254,410) x common factors =2 x 1 = 2

LCM(254,410) = ( 254 × 410 ) / 2

LCM(254,410) = 104140 / 2

LCM(254,410) = 52070
