Greatest Common Factor

We found the factors 57,720,795 . The biggest common factor number is the GCF number.
So the greatest common factor 57,720,795 is 3.

Lets's calculate LCM of 21,76,654

2 21, 76, 654
3 21, 38, 327
7, 38, 109

∴ So the LCM of the given numbers is 2 x 3 x 7 x 38 x 109 = 173964

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/173964

Therefore, the GCF of Fractions 57/21,720/76,795/654 is 3/173964

Least Common Multiple of 21,76,654 with GCF Formula

Least Common Multiple of 21,76,654 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 21,76,654 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,76,654) = 1

common factors(in case of two or more numbers have common factors) = 6

GCF(21,76,654) x common factors =1 x 6 = 6

LCM(21,76,654) = ( 21 × 76 × 654 ) / 6

LCM(21,76,654) = 1043784 / 6

LCM(21,76,654) = 173964
