Greatest Common Factor
We found the factors 240,685 . The biggest common factor number is the GCF number.
So the greatest common factor 240,685 is 5.
Lets's calculate LCM of 128,713
Given numbers has no common factors except 1. So, there LCM is their product i.e 91264
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/91264
Therefore, the GCF of Fractions 240/128,685/713 is 5/91264
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 128,713 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(128,713) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(128,713) x common factors =1 x 1 = 1
LCM(128,713) = ( 128 × 713 ) / 1
LCM(128,713) = 91264 / 1
LCM(128,713) = 91264
