The HCF of 247,231 is 1.
Lets's calculate GCF of 247,231
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 247
:1,13,19,247
Now, list down the factors of 231
:1,3,7,11,21,33,77,231
Greatest Common Factor
We found the factors 247,231 . The biggest common factor number is the GCF number.
So the greatest common factor 247,231 is 1.
Lets's calculate LCM of 159,558
3 | 159, 558 |
53, 186 |
∴ So the LCM of the given numbers is 3 x 53 x 186 = 29574
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/29574
Therefore, the GCF of Fractions 247/159,231/558 is 1/29574
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 159,558 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(159,558) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(159,558) x common factors =3 x 1 = 3
LCM(159,558) = ( 159 × 558 ) / 3
LCM(159,558) = 88722 / 3
LCM(159,558) = 29574
