Lets's calculate GCF of 276,286
2 | 276, 286 |
138, 143 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 276
:1,2,3,4,6,12,23,46,69,92,138,276
Now, list down the factors of 286
:1,2,11,13,22,26,143,286
Greatest Common Factor
We found the factors 276,286 . The biggest common factor number is the GCF number.
So the greatest common factor 276,286 is 2.
Lets's calculate LCM of 15,981
3 | 15, 981 |
5, 327 |
∴ So the LCM of the given numbers is 3 x 5 x 327 = 4905
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/4905
Therefore, the GCF of Fractions 276/15,286/981 is 2/4905
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 15,981 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,981) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(15,981) x common factors =3 x 1 = 3
LCM(15,981) = ( 15 × 981 ) / 3
LCM(15,981) = 14715 / 3
LCM(15,981) = 4905
