Lets's calculate GCF of 711,927
3 | 711, 927 |
3 | 237, 309 |
79, 103 |
∴ So the GCF of the given numbers is 3 x 3 = 9
Now, list down the factors of 711
:1,3,9,79,237,711
Now, list down the factors of 927
:1,3,9,103,309,927
Greatest Common Factor
We found the factors 711,927 . The biggest common factor number is the GCF number.
So the greatest common factor 711,927 is 9.
Lets's calculate LCM of 213,561
3 | 213, 561 |
71, 187 |
∴ So the LCM of the given numbers is 3 x 71 x 187 = 39831
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/39831
Therefore, the GCF of Fractions 711/213,927/561 is 9/39831
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 213,561 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(213,561) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(213,561) x common factors =3 x 1 = 3
LCM(213,561) = ( 213 × 561 ) / 3
LCM(213,561) = 119493 / 3
LCM(213,561) = 39831
