So the greatest common factor 403,969 is 1.
Lets's calculate LCM of 961,491
Given numbers has no common factors except 1. So, there LCM is their product i.e 471851
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/471851
Therefore, the GCF of Fractions 403/961,969/491 is 1/471851
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 961,491 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(961,491) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(961,491) x common factors =1 x 1 = 1
LCM(961,491) = ( 961 × 491 ) / 1
LCM(961,491) = 471851 / 1
LCM(961,491) = 471851
