Greatest Common Factor
We found the factors 3971,8786 . The biggest common factor number is the GCF number.
So the greatest common factor 3971,8786 is 1.
Lets's calculate LCM of 728,687
Given numbers has no common factors except 1. So, there LCM is their product i.e 500136
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/500136
Therefore, the GCF of Fractions 3971/728,8786/687 is 1/500136
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 728,687 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(728,687) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(728,687) x common factors =1 x 1 = 1
LCM(728,687) = ( 728 × 687 ) / 1
LCM(728,687) = 500136 / 1
LCM(728,687) = 500136
