Greatest Common Factor
We found the factors 800,788 . The biggest common factor number is the GCF number.
So the greatest common factor 800,788 is 4.
Lets's calculate LCM of 647,378
Given numbers has no common factors except 1. So, there LCM is their product i.e 244566
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/244566
Therefore, the GCF of Fractions 800/647,788/378 is 4/244566
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 647,378 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(647,378) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(647,378) x common factors =1 x 1 = 1
LCM(647,378) = ( 647 × 378 ) / 1
LCM(647,378) = 244566 / 1
LCM(647,378) = 244566
