So the greatest common factor 767,972 is 1.
Lets's calculate LCM of 256,257
Given numbers has no common factors except 1. So, there LCM is their product i.e 65792
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/65792
Therefore, the GCF of Fractions 767/256,972/257 is 1/65792
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 256,257 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(256,257) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(256,257) x common factors =1 x 1 = 1
LCM(256,257) = ( 256 × 257 ) / 1
LCM(256,257) = 65792 / 1
LCM(256,257) = 65792
