Lets's calculate LCM of 505,238
Given numbers has no common factors except 1. So, there LCM is their product i.e 120190
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/120190
Therefore, the GCF of Fractions 890/505,7788/238 is 2/120190
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 505,238 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(505,238) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(505,238) x common factors =1 x 1 = 1
LCM(505,238) = ( 505 × 238 ) / 1
LCM(505,238) = 120190 / 1
LCM(505,238) = 120190
