Now, list down the factors of 305
:1,5,61,305
Greatest Common Factor
We found the factors 623,305 . The biggest common factor number is the GCF number.
So the greatest common factor 623,305 is 1.
Lets's calculate LCM of 83,385
Given numbers has no common factors except 1. So, there LCM is their product i.e 31955
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/31955
Therefore, the GCF of Fractions 623/83,305/385 is 1/31955
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 83,385 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(83,385) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(83,385) x common factors =1 x 1 = 1
LCM(83,385) = ( 83 × 385 ) / 1
LCM(83,385) = 31955 / 1
LCM(83,385) = 31955
