Lets's calculate LCM of 516,617
Given numbers has no common factors except 1. So, there LCM is their product i.e 318372
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/318372
Therefore, the GCF of Fractions 788/516,687/617 is 1/318372
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 516,617 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(516,617) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(516,617) x common factors =1 x 1 = 1
LCM(516,617) = ( 516 × 617 ) / 1
LCM(516,617) = 318372 / 1
LCM(516,617) = 318372
