Greatest Common Factor
We found the factors 3640,9940 . The biggest common factor number is the GCF number.
So the greatest common factor 3640,9940 is 140.
Lets's calculate LCM of 400,7291
Given numbers has no common factors except 1. So, there LCM is their product i.e 2916400
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 140/2916400
Therefore, the GCF of Fractions 3640/400,9940/7291 is 140/2916400
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 400,7291 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(400,7291) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(400,7291) x common factors =1 x 1 = 1
LCM(400,7291) = ( 400 × 7291 ) / 1
LCM(400,7291) = 2916400 / 1
LCM(400,7291) = 2916400
