Lets's calculate GCF of 100,555
5 | 100, 555 |
20, 111 |
∴ So the GCF of the given numbers is 5 = 5
Now, list down the factors of 100
:1,2,4,5,10,20,25,50,100
Now, list down the factors of 555
:1,3,5,15,37,111,185,555
Greatest Common Factor
We found the factors 100,555 . The biggest common factor number is the GCF number.
So the greatest common factor 100,555 is 5.
Lets's calculate LCM of 417,816
3 | 417, 816 |
139, 272 |
∴ So the LCM of the given numbers is 3 x 139 x 272 = 113424
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/113424
Therefore, the GCF of Fractions 100/417,555/816 is 5/113424
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 417,816 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(417,816) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(417,816) x common factors =3 x 1 = 3
LCM(417,816) = ( 417 × 816 ) / 3
LCM(417,816) = 340272 / 3
LCM(417,816) = 113424
