:1,7,13,49,91,637
Greatest Common Factor
We found the factors 338,637 . The biggest common factor number is the GCF number.
So the greatest common factor 338,637 is 13.
Lets's calculate LCM of 415,676
Given numbers has no common factors except 1. So, there LCM is their product i.e 280540
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 13/280540
Therefore, the GCF of Fractions 338/415,637/676 is 13/280540
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 415,676 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(415,676) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(415,676) x common factors =1 x 1 = 1
LCM(415,676) = ( 415 × 676 ) / 1
LCM(415,676) = 280540 / 1
LCM(415,676) = 280540
