So the greatest common factor 304,980 is 4.
Lets's calculate LCM of 921,698
Given numbers has no common factors except 1. So, there LCM is their product i.e 642858
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/642858
Therefore, the GCF of Fractions 304/921,980/698 is 4/642858
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 921,698 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(921,698) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(921,698) x common factors =1 x 1 = 1
LCM(921,698) = ( 921 × 698 ) / 1
LCM(921,698) = 642858 / 1
LCM(921,698) = 642858
