2 | 518, 786 |
259, 393 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 518
:1,2,7,14,37,74,259,518
Now, list down the factors of 786
:1,2,3,6,131,262,393,786
Greatest Common Factor
We found the factors 518,786 . The biggest common factor number is the GCF number.
So the greatest common factor 518,786 is 2.
Lets's calculate LCM of 54,720
2 | 54, 720 |
3 | 27, 360 |
3 | 9, 120 |
3, 40 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 3 x 40 = 2160
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/2160
Therefore, the GCF of Fractions 518/54,786/720 is 2/2160
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 54,720 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(54,720) = 18
common factors(in case of two or more numbers have common factors) = 1
GCF(54,720) x common factors =18 x 1 = 18
LCM(54,720) = ( 54 × 720 ) / 18
LCM(54,720) = 38880 / 18
LCM(54,720) = 2160
