Lets's calculate GCF of 328,652
2 | 328, 652 |
2 | 164, 326 |
82, 163 |
∴ So the GCF of the given numbers is 2 x 2 = 4
Now, list down the factors of 328
:1,2,4,8,41,82,164,328
Now, list down the factors of 652
:1,2,4,163,326,652
Greatest Common Factor
We found the factors 328,652 . The biggest common factor number is the GCF number.
So the greatest common factor 328,652 is 4.
Lets's calculate LCM of 21,249
3 | 21, 249 |
7, 83 |
∴ So the LCM of the given numbers is 3 x 7 x 83 = 1743
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/1743
Therefore, the GCF of Fractions 328/21,652/249 is 4/1743
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 21,249 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,249) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(21,249) x common factors =3 x 1 = 3
LCM(21,249) = ( 21 × 249 ) / 3
LCM(21,249) = 5229 / 3
LCM(21,249) = 1743
