Lets's calculate GCF of 434,886
2 | 434, 886 |
217, 443 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 434
:1,2,7,14,31,62,217,434
Now, list down the factors of 886
:1,2,443,886
Greatest Common Factor
We found the factors 434,886 . The biggest common factor number is the GCF number.
So the greatest common factor 434,886 is 2.
Lets's calculate LCM of 81,723
3 | 81, 723 |
27, 241 |
∴ So the LCM of the given numbers is 3 x 27 x 241 = 19521
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/19521
Therefore, the GCF of Fractions 434/81,886/723 is 2/19521
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 81,723 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,723) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(81,723) x common factors =3 x 1 = 3
LCM(81,723) = ( 81 × 723 ) / 3
LCM(81,723) = 58563 / 3
LCM(81,723) = 19521
