:1,2,3,6,43,86,129,258
Greatest Common Factor
We found the factors 396,258 . The biggest common factor number is the GCF number.
So the greatest common factor 396,258 is 6.
Lets's calculate LCM of 573,145
Given numbers has no common factors except 1. So, there LCM is their product i.e 83085
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/83085
Therefore, the GCF of Fractions 396/573,258/145 is 6/83085
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 573,145 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(573,145) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(573,145) x common factors =1 x 1 = 1
LCM(573,145) = ( 573 × 145 ) / 1
LCM(573,145) = 83085 / 1
LCM(573,145) = 83085
