So the greatest common factor 672,210 is 42.
Lets's calculate LCM of 783,275
Given numbers has no common factors except 1. So, there LCM is their product i.e 215325
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 42/215325
Therefore, the GCF of Fractions 672/783,210/275 is 42/215325
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 783,275 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(783,275) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(783,275) x common factors =1 x 1 = 1
LCM(783,275) = ( 783 × 275 ) / 1
LCM(783,275) = 215325 / 1
LCM(783,275) = 215325
