:1,2,5,10,43,86,215,430
Now, list down the factors of 289
:1,17,289
Greatest Common Factor
We found the factors 430,289 . The biggest common factor number is the GCF number.
So the greatest common factor 430,289 is 1.
Lets's calculate LCM of 981,205
Given numbers has no common factors except 1. So, there LCM is their product i.e 201105
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/201105
Therefore, the GCF of Fractions 430/981,289/205 is 1/201105
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 981,205 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(981,205) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(981,205) x common factors =1 x 1 = 1
LCM(981,205) = ( 981 × 205 ) / 1
LCM(981,205) = 201105 / 1
LCM(981,205) = 201105
