Greatest Common Factor

We found the factors 2,85,12 . The biggest common factor number is the GCF number.
So the greatest common factor 2,85,12 is 1.

Lets's calculate LCM of 34,646,215

2 34, 646, 215
17 17, 323, 215
1, 19, 215

∴ So the LCM of the given numbers is 2 x 17 x 1 x 19 x 215 = 138890

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/138890

Therefore, the GCF of Fractions 2/34,85/646,12/215 is 1/138890

Least Common Multiple of 34,646,215 with GCF Formula

Least Common Multiple of 34,646,215 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 34,646,215 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(34,646,215) = 1

common factors(in case of two or more numbers have common factors) = 34

GCF(34,646,215) x common factors =1 x 34 = 34

LCM(34,646,215) = ( 34 × 646 × 215 ) / 34

LCM(34,646,215) = 4722260 / 34

LCM(34,646,215) = 138890
