So the greatest common factor 993,816 is 3.
Lets's calculate LCM of 918,689
Given numbers has no common factors except 1. So, there LCM is their product i.e 632502
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/632502
Therefore, the GCF of Fractions 993/918,816/689 is 3/632502
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 918,689 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(918,689) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(918,689) x common factors =1 x 1 = 1
LCM(918,689) = ( 918 × 689 ) / 1
LCM(918,689) = 632502 / 1
LCM(918,689) = 632502
