Lets's calculate LCM of 78,647
Given numbers has no common factors except 1. So, there LCM is their product i.e 50466
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/50466
Therefore, the GCF of Fractions 510/78,688/647 is 2/50466
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 78,647 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,647) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(78,647) x common factors =1 x 1 = 1
LCM(78,647) = ( 78 × 647 ) / 1
LCM(78,647) = 50466 / 1
LCM(78,647) = 50466
