Lets's calculate LCM of 185,249
Given numbers has no common factors except 1. So, there LCM is their product i.e 46065
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/46065
Therefore, the GCF of Fractions 392/185,155/249 is 1/46065
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 185,249 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(185,249) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(185,249) x common factors =1 x 1 = 1
LCM(185,249) = ( 185 × 249 ) / 1
LCM(185,249) = 46065 / 1
LCM(185,249) = 46065
