Lets's calculate GCF of 405,135
3 | 405, 135 |
3 | 135, 45 |
3 | 15, 45 |
5 | 5, 15 |
1, 3 |
∴ So the GCF of the given numbers is 3 x 3 x 3 x 5 = 135
Now, list down the factors of 405
:1,3,5,9,15,27,45,81,135,405
Now, list down the factors of 135
:1,3,5,9,15,27,45,135
Greatest Common Factor
We found the factors 405,135 . The biggest common factor number is the GCF number.
So the greatest common factor 405,135 is 135.
Lets's calculate LCM of 159,516
3 | 159, 516 |
53, 172 |
∴ So the LCM of the given numbers is 3 x 53 x 172 = 27348
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 135/27348
Therefore, the GCF of Fractions 405/159,135/516 is 135/27348
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 159,516 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(159,516) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(159,516) x common factors =3 x 1 = 3
LCM(159,516) = ( 159 × 516 ) / 3
LCM(159,516) = 82044 / 3
LCM(159,516) = 27348
