So the greatest common factor 128,675 is 1.
Lets's calculate LCM of 931,425
Given numbers has no common factors except 1. So, there LCM is their product i.e 395675
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/395675
Therefore, the GCF of Fractions 128/931,675/425 is 1/395675
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 931,425 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(931,425) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(931,425) x common factors =1 x 1 = 1
LCM(931,425) = ( 931 × 425 ) / 1
LCM(931,425) = 395675 / 1
LCM(931,425) = 395675
