Greatest Common Factor
We found the factors 342,858 . The biggest common factor number is the GCF number.
So the greatest common factor 342,858 is 6.
Lets's calculate LCM of 19,693
Given numbers has no common factors except 1. So, there LCM is their product i.e 13167
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/13167
Therefore, the GCF of Fractions 342/19,858/693 is 6/13167
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 19,693 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,693) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(19,693) x common factors =1 x 1 = 1
LCM(19,693) = ( 19 × 693 ) / 1
LCM(19,693) = 13167 / 1
LCM(19,693) = 13167
