Greatest Common Factor
We found the factors 168,471 . The biggest common factor number is the GCF number.
So the greatest common factor 168,471 is 3.
Lets's calculate LCM of 257,110
Given numbers has no common factors except 1. So, there LCM is their product i.e 28270
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/28270
Therefore, the GCF of Fractions 168/257,471/110 is 3/28270
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 257,110 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(257,110) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(257,110) x common factors =1 x 1 = 1
LCM(257,110) = ( 257 × 110 ) / 1
LCM(257,110) = 28270 / 1
LCM(257,110) = 28270
