Now, list down the factors of 455
:1,5,7,13,35,65,91,455
Greatest Common Factor
We found the factors 421,455 . The biggest common factor number is the GCF number.
So the greatest common factor 421,455 is 1.
Lets's calculate LCM of 166,921
Given numbers has no common factors except 1. So, there LCM is their product i.e 152886
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/152886
Therefore, the GCF of Fractions 421/166,455/921 is 1/152886
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 166,921 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(166,921) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(166,921) x common factors =1 x 1 = 1
LCM(166,921) = ( 166 × 921 ) / 1
LCM(166,921) = 152886 / 1
LCM(166,921) = 152886
