Lets's calculate LCM of 647,486
Given numbers has no common factors except 1. So, there LCM is their product i.e 314442
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/314442
Therefore, the GCF of Fractions 470/647,772/486 is 2/314442
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 647,486 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(647,486) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(647,486) x common factors =1 x 1 = 1
LCM(647,486) = ( 647 × 486 ) / 1
LCM(647,486) = 314442 / 1
LCM(647,486) = 314442
