So the greatest common factor 279,210 is 3.
Lets's calculate LCM of 99,257
Given numbers has no common factors except 1. So, there LCM is their product i.e 25443
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/25443
Therefore, the GCF of Fractions 279/99,210/257 is 3/25443
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 99,257 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(99,257) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(99,257) x common factors =1 x 1 = 1
LCM(99,257) = ( 99 × 257 ) / 1
LCM(99,257) = 25443 / 1
LCM(99,257) = 25443
