Greatest Common Factor
We found the factors 856,839 . The biggest common factor number is the GCF number.
So the greatest common factor 856,839 is 1.
Lets's calculate LCM of 129,257
Given numbers has no common factors except 1. So, there LCM is their product i.e 33153
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/33153
Therefore, the GCF of Fractions 856/129,839/257 is 1/33153
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 129,257 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(129,257) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(129,257) x common factors =1 x 1 = 1
LCM(129,257) = ( 129 × 257 ) / 1
LCM(129,257) = 33153 / 1
LCM(129,257) = 33153
