Greatest Common Factor
We found the factors 867,931 . The biggest common factor number is the GCF number.
So the greatest common factor 867,931 is 1.
Lets's calculate LCM of 208,397
Given numbers has no common factors except 1. So, there LCM is their product i.e 82576
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/82576
Therefore, the GCF of Fractions 867/208,931/397 is 1/82576
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 208,397 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(208,397) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(208,397) x common factors =1 x 1 = 1
LCM(208,397) = ( 208 × 397 ) / 1
LCM(208,397) = 82576 / 1
LCM(208,397) = 82576
