Lets's calculate LCM of 936,337
Given numbers has no common factors except 1. So, there LCM is their product i.e 315432
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 18/315432
Therefore, the GCF of Fractions 684/936,990/337 is 18/315432
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 936,337 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(936,337) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(936,337) x common factors =1 x 1 = 1
LCM(936,337) = ( 936 × 337 ) / 1
LCM(936,337) = 315432 / 1
LCM(936,337) = 315432
