Lets's calculate LCM of 961,630
Given numbers has no common factors except 1. So, there LCM is their product i.e 605430
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/605430
Therefore, the GCF of Fractions 676/961,438/630 is 2/605430
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 961,630 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(961,630) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(961,630) x common factors =1 x 1 = 1
LCM(961,630) = ( 961 × 630 ) / 1
LCM(961,630) = 605430 / 1
LCM(961,630) = 605430
