Lets's calculate LCM of 799,409
Given numbers has no common factors except 1. So, there LCM is their product i.e 326791
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/326791
Therefore, the GCF of Fractions 790/799,6378/409 is 2/326791
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 799,409 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(799,409) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(799,409) x common factors =1 x 1 = 1
LCM(799,409) = ( 799 × 409 ) / 1
LCM(799,409) = 326791 / 1
LCM(799,409) = 326791
