So the greatest common factor 777,462 is 21.
Lets's calculate LCM of 985,645
5 | 985, 645 |
197, 129 |
∴ So the LCM of the given numbers is 5 x 197 x 129 = 127065
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 21/127065
Therefore, the GCF of Fractions 777/985,462/645 is 21/127065
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 985,645 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(985,645) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(985,645) x common factors =5 x 1 = 5
LCM(985,645) = ( 985 × 645 ) / 5
LCM(985,645) = 635325 / 5
LCM(985,645) = 127065
