So the greatest common factor 758,621 is 1.
Lets's calculate LCM of 55,7981
Given numbers has no common factors except 1. So, there LCM is their product i.e 438955
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/438955
Therefore, the GCF of Fractions 758/55,621/7981 is 1/438955
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 55,7981 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(55,7981) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(55,7981) x common factors =1 x 1 = 1
LCM(55,7981) = ( 55 × 7981 ) / 1
LCM(55,7981) = 438955 / 1
LCM(55,7981) = 438955
