Lets's calculate GCF of 903,990
3 | 903, 990 |
301, 330 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 903
:1,3,7,21,43,129,301,903
Now, list down the factors of 990
:1,2,3,5,6,9,10,11,15,18,22,30,33,45,55,66,90,99,110,165,198,330,495,990
Greatest Common Factor
We found the factors 903,990 . The biggest common factor number is the GCF number.
So the greatest common factor 903,990 is 3.
Lets's calculate LCM of 637,104
13 | 637, 104 |
49, 8 |
∴ So the LCM of the given numbers is 13 x 49 x 8 = 5096
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/5096
Therefore, the GCF of Fractions 903/637,990/104 is 3/5096
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 637,104 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(637,104) = 13
common factors(in case of two or more numbers have common factors) = 1
GCF(637,104) x common factors =13 x 1 = 13
LCM(637,104) = ( 637 × 104 ) / 13
LCM(637,104) = 66248 / 13
LCM(637,104) = 5096
