So the greatest common factor 918,120 is 6.
Lets's calculate LCM of 641,388
Given numbers has no common factors except 1. So, there LCM is their product i.e 248708
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/248708
Therefore, the GCF of Fractions 918/641,120/388 is 6/248708
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 641,388 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(641,388) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(641,388) x common factors =1 x 1 = 1
LCM(641,388) = ( 641 × 388 ) / 1
LCM(641,388) = 248708 / 1
LCM(641,388) = 248708
