Lets's calculate LCM of 474,491
Given numbers has no common factors except 1. So, there LCM is their product i.e 232734
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/232734
Therefore, the GCF of Fractions 832/474,3940/491 is 4/232734
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 474,491 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(474,491) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(474,491) x common factors =1 x 1 = 1
LCM(474,491) = ( 474 × 491 ) / 1
LCM(474,491) = 232734 / 1
LCM(474,491) = 232734
