The factors of 873 are 1, 3, 9, 97, 291, 873
The HCF of 811,873 is 1.
Lets's calculate GCF of 811,873
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 811
:1,811
Now, list down the factors of 873
:1,3,9,97,291,873
Greatest Common Factor
We found the factors 811,873 . The biggest common factor number is the GCF number.
So the greatest common factor 811,873 is 1.
Lets's calculate LCM of 646,197
Given numbers has no common factors except 1. So, there LCM is their product i.e 127262
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/127262
Therefore, the GCF of Fractions 811/646,873/197 is 1/127262
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 646,197 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(646,197) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(646,197) x common factors =1 x 1 = 1
LCM(646,197) = ( 646 × 197 ) / 1
LCM(646,197) = 127262 / 1
LCM(646,197) = 127262
