Lets's calculate LCM of 639,6569
Given numbers has no common factors except 1. So, there LCM is their product i.e 4197591
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4197591
Therefore, the GCF of Fractions 778/639,7657/6569 is 1/4197591
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 639,6569 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(639,6569) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(639,6569) x common factors =1 x 1 = 1
LCM(639,6569) = ( 639 × 6569 ) / 1
LCM(639,6569) = 4197591 / 1
LCM(639,6569) = 4197591
