Lets's calculate LCM of 637,645,591
3 | 637, 645, 591 |
637, 215, 197 |
∴ So the LCM of the given numbers is 3 x 637 x 215 x 197 = 80940405
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/80940405
Therefore, the GCF of Fractions 56/637,39/645,660/591 is 1/80940405
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 637,645,591 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(637,645,591) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(637,645,591) x common factors =1 x 3 = 3
LCM(637,645,591) = ( 637 × 645 × 591 ) / 3
LCM(637,645,591) = 242821215 / 3
LCM(637,645,591) = 80940405
