So the greatest common factor 117,693 is 9.
Lets's calculate LCM of 620,665
5 | 620, 665 |
124, 133 |
∴ So the LCM of the given numbers is 5 x 124 x 133 = 82460
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/82460
Therefore, the GCF of Fractions 117/620,693/665 is 9/82460
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 620,665 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(620,665) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(620,665) x common factors =5 x 1 = 5
LCM(620,665) = ( 620 × 665 ) / 5
LCM(620,665) = 412300 / 5
LCM(620,665) = 82460
