So the greatest common factor 705,498 is 3.
Lets's calculate LCM of 435,394
Given numbers has no common factors except 1. So, there LCM is their product i.e 171390
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/171390
Therefore, the GCF of Fractions 705/435,498/394 is 3/171390
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 435,394 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(435,394) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(435,394) x common factors =1 x 1 = 1
LCM(435,394) = ( 435 × 394 ) / 1
LCM(435,394) = 171390 / 1
LCM(435,394) = 171390
