Greatest Common Factor
We found the factors 357,336 . The biggest common factor number is the GCF number.
So the greatest common factor 357,336 is 21.
Lets's calculate LCM of 165,853
Given numbers has no common factors except 1. So, there LCM is their product i.e 140745
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 21/140745
Therefore, the GCF of Fractions 357/165,336/853 is 21/140745
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 165,853 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(165,853) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(165,853) x common factors =1 x 1 = 1
LCM(165,853) = ( 165 × 853 ) / 1
LCM(165,853) = 140745 / 1
LCM(165,853) = 140745
