Lets's calculate LCM of 423,904
Given numbers has no common factors except 1. So, there LCM is their product i.e 382392
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/382392
Therefore, the GCF of Fractions 847/423,9660/904 is 7/382392
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 423,904 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(423,904) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(423,904) x common factors =1 x 1 = 1
LCM(423,904) = ( 423 × 904 ) / 1
LCM(423,904) = 382392 / 1
LCM(423,904) = 382392
