Lets's calculate LCM of 309,245
Given numbers has no common factors except 1. So, there LCM is their product i.e 75705
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/75705
Therefore, the GCF of Fractions 326/309,690/245 is 2/75705
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 309,245 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(309,245) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(309,245) x common factors =1 x 1 = 1
LCM(309,245) = ( 309 × 245 ) / 1
LCM(309,245) = 75705 / 1
LCM(309,245) = 75705
