Lets's calculate LCM of 316,491
Given numbers has no common factors except 1. So, there LCM is their product i.e 155156
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/155156
Therefore, the GCF of Fractions 874/316,790/491 is 2/155156
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 316,491 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(316,491) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(316,491) x common factors =1 x 1 = 1
LCM(316,491) = ( 316 × 491 ) / 1
LCM(316,491) = 155156 / 1
LCM(316,491) = 155156
