Greatest Common Factor
We found the factors 650,820 . The biggest common factor number is the GCF number.
So the greatest common factor 650,820 is 10.
Lets's calculate LCM of 434,691
Given numbers has no common factors except 1. So, there LCM is their product i.e 299894
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/299894
Therefore, the GCF of Fractions 650/434,820/691 is 10/299894
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 434,691 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(434,691) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(434,691) x common factors =1 x 1 = 1
LCM(434,691) = ( 434 × 691 ) / 1
LCM(434,691) = 299894 / 1
LCM(434,691) = 299894
