Lets's calculate LCM of 359,486
Given numbers has no common factors except 1. So, there LCM is their product i.e 174474
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/174474
Therefore, the GCF of Fractions 198/359,646/486 is 2/174474
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 359,486 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(359,486) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(359,486) x common factors =1 x 1 = 1
LCM(359,486) = ( 359 × 486 ) / 1
LCM(359,486) = 174474 / 1
LCM(359,486) = 174474
