So the greatest common factor 688,885 is 1.
Lets's calculate LCM of 395,108
Given numbers has no common factors except 1. So, there LCM is their product i.e 42660
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/42660
Therefore, the GCF of Fractions 688/395,885/108 is 1/42660
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 395,108 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(395,108) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(395,108) x common factors =1 x 1 = 1
LCM(395,108) = ( 395 × 108 ) / 1
LCM(395,108) = 42660 / 1
LCM(395,108) = 42660
