∴ So the GCF of the given numbers is 71 = 71
Now, list down the factors of 639
:1,3,9,71,213,639
Now, list down the factors of 355
:1,5,71,355
Greatest Common Factor
We found the factors 639,355 . The biggest common factor number is the GCF number.
So the greatest common factor 639,355 is 71.
Lets's calculate LCM of 698,113
Given numbers has no common factors except 1. So, there LCM is their product i.e 78874
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 71/78874
Therefore, the GCF of Fractions 639/698,355/113 is 71/78874
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 698,113 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(698,113) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(698,113) x common factors =1 x 1 = 1
LCM(698,113) = ( 698 × 113 ) / 1
LCM(698,113) = 78874 / 1
LCM(698,113) = 78874
