So the greatest common factor 972,920 is 4.
Lets's calculate LCM of 347,819
Given numbers has no common factors except 1. So, there LCM is their product i.e 284193
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/284193
Therefore, the GCF of Fractions 972/347,920/819 is 4/284193
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 347,819 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(347,819) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(347,819) x common factors =1 x 1 = 1
LCM(347,819) = ( 347 × 819 ) / 1
LCM(347,819) = 284193 / 1
LCM(347,819) = 284193
