Lets's calculate LCM of 993,8405
Given numbers has no common factors except 1. So, there LCM is their product i.e 8346165
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/8346165
Therefore, the GCF of Fractions 1292/993,7997/8405 is 1/8346165
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 993,8405 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(993,8405) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(993,8405) x common factors =1 x 1 = 1
LCM(993,8405) = ( 993 × 8405 ) / 1
LCM(993,8405) = 8346165 / 1
LCM(993,8405) = 8346165
