Lets's calculate LCM of 391,245
Given numbers has no common factors except 1. So, there LCM is their product i.e 95795
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/95795
Therefore, the GCF of Fractions 424/391,7485/245 is 1/95795
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 391,245 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(391,245) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(391,245) x common factors =1 x 1 = 1
LCM(391,245) = ( 391 × 245 ) / 1
LCM(391,245) = 95795 / 1
LCM(391,245) = 95795
