Lets's calculate LCM of 235,668
Given numbers has no common factors except 1. So, there LCM is their product i.e 156980
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/156980
Therefore, the GCF of Fractions 256/235,561/668 is 1/156980
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 235,668 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(235,668) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(235,668) x common factors =1 x 1 = 1
LCM(235,668) = ( 235 × 668 ) / 1
LCM(235,668) = 156980 / 1
LCM(235,668) = 156980
