So the greatest common factor 817,140 is 1.
Lets's calculate LCM of 423,385
Given numbers has no common factors except 1. So, there LCM is their product i.e 162855
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/162855
Therefore, the GCF of Fractions 817/423,140/385 is 1/162855
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 423,385 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(423,385) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(423,385) x common factors =1 x 1 = 1
LCM(423,385) = ( 423 × 385 ) / 1
LCM(423,385) = 162855 / 1
LCM(423,385) = 162855
