We found the factors 878,381 . The biggest common factor number is the GCF number.
So the greatest common factor 878,381 is 1.
Lets's calculate LCM of 393,698
Given numbers has no common factors except 1. So, there LCM is their product i.e 274314
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/274314
Therefore, the GCF of Fractions 878/393,381/698 is 1/274314
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 393,698 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(393,698) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(393,698) x common factors =1 x 1 = 1
LCM(393,698) = ( 393 × 698 ) / 1
LCM(393,698) = 274314 / 1
LCM(393,698) = 274314
