Lets's calculate GCF of 813,141
3 | 813, 141 |
271, 47 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 813
:1,3,271,813
Now, list down the factors of 141
:1,3,47,141
Greatest Common Factor
We found the factors 813,141 . The biggest common factor number is the GCF number.
So the greatest common factor 813,141 is 3.
Lets's calculate LCM of 273,273
3 | 273, 273 |
7 | 91, 91 |
13 | 13, 13 |
1, 1 |
∴ So the LCM of the given numbers is 3 x 7 x 13 x 1 x 1 = 273
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/273
Therefore, the GCF of Fractions 813/273,141/273 is 3/273
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 273,273 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(273,273) = 273
common factors(in case of two or more numbers have common factors) = 1
GCF(273,273) x common factors =273 x 1 = 273
LCM(273,273) = ( 273 × 273 ) / 273
LCM(273,273) = 74529 / 273
LCM(273,273) = 273
