Lets's calculate GCF of 243,873
3 | 243, 873 |
3 | 81, 291 |
27, 97 |
∴ So the GCF of the given numbers is 3 x 3 = 9
Now, list down the factors of 243
:1,3,9,27,81,243
Now, list down the factors of 873
:1,3,9,97,291,873
Greatest Common Factor
We found the factors 243,873 . The biggest common factor number is the GCF number.
So the greatest common factor 243,873 is 9.
Lets's calculate LCM of 887,462
Given numbers has no common factors except 1. So, there LCM is their product i.e 409794
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/409794
Therefore, the GCF of Fractions 243/887,873/462 is 9/409794
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 887,462 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(887,462) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(887,462) x common factors =1 x 1 = 1
LCM(887,462) = ( 887 × 462 ) / 1
LCM(887,462) = 409794 / 1
LCM(887,462) = 409794
