:1,2,3,5,6,10,15,30,31,62,93,155,186,310,465,930
Greatest Common Factor
We found the factors 422,930 . The biggest common factor number is the GCF number.
So the greatest common factor 422,930 is 2.
Lets's calculate LCM of 781,161
Given numbers has no common factors except 1. So, there LCM is their product i.e 125741
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/125741
Therefore, the GCF of Fractions 422/781,930/161 is 2/125741
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 781,161 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(781,161) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(781,161) x common factors =1 x 1 = 1
LCM(781,161) = ( 781 × 161 ) / 1
LCM(781,161) = 125741 / 1
LCM(781,161) = 125741
