So the greatest common factor 494,612 is 2.
Lets's calculate LCM of 170,757
Given numbers has no common factors except 1. So, there LCM is their product i.e 128690
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/128690
Therefore, the GCF of Fractions 494/170,612/757 is 2/128690
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 170,757 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(170,757) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(170,757) x common factors =1 x 1 = 1
LCM(170,757) = ( 170 × 757 ) / 1
LCM(170,757) = 128690 / 1
LCM(170,757) = 128690
