Lets's calculate LCM of 181,949
Given numbers has no common factors except 1. So, there LCM is their product i.e 171769
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/171769
Therefore, the GCF of Fractions 665/181,868/949 is 7/171769
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 181,949 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(181,949) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(181,949) x common factors =1 x 1 = 1
LCM(181,949) = ( 181 × 949 ) / 1
LCM(181,949) = 171769 / 1
LCM(181,949) = 171769
