Greatest Common Factor
We found the factors 9920,4620 . The biggest common factor number is the GCF number.
So the greatest common factor 9920,4620 is 20.
Lets's calculate LCM of 769,745
Given numbers has no common factors except 1. So, there LCM is their product i.e 572905
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 20/572905
Therefore, the GCF of Fractions 9920/769,4620/745 is 20/572905
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 769,745 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(769,745) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(769,745) x common factors =1 x 1 = 1
LCM(769,745) = ( 769 × 745 ) / 1
LCM(769,745) = 572905 / 1
LCM(769,745) = 572905
