So the greatest common factor 172,392 is 4.
Lets's calculate LCM of 173,343
Given numbers has no common factors except 1. So, there LCM is their product i.e 59339
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/59339
Therefore, the GCF of Fractions 172/173,392/343 is 4/59339
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 173,343 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(173,343) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(173,343) x common factors =1 x 1 = 1
LCM(173,343) = ( 173 × 343 ) / 1
LCM(173,343) = 59339 / 1
LCM(173,343) = 59339
