Therefore, the GCF of Fractions 845/392,2798/7791 is 1/62328
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 392,7791 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(392,7791) = 49
common factors(in case of two or more numbers have common factors) = 1
GCF(392,7791) x common factors =49 x 1 = 49
LCM(392,7791) = ( 392 × 7791 ) / 49
LCM(392,7791) = 3054072 / 49
LCM(392,7791) = 62328
