So the greatest common factor 523,656 is 1.
Lets's calculate LCM of 613,137
Given numbers has no common factors except 1. So, there LCM is their product i.e 83981
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/83981
Therefore, the GCF of Fractions 523/613,656/137 is 1/83981
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 613,137 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(613,137) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(613,137) x common factors =1 x 1 = 1
LCM(613,137) = ( 613 × 137 ) / 1
LCM(613,137) = 83981 / 1
LCM(613,137) = 83981
