The factors of 17 are 1, 17
The HCF of 33,67,17 is 1.
Lets's calculate GCF of 33,67,17
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 33
:1,3,11,33
Now, list down the factors of 67
:1,67
Now, list down the factors of 17
:1,17
Greatest Common Factor
We found the factors 33,67,17 . The biggest common factor number is the GCF number.
So the greatest common factor 33,67,17 is 1.
Lets's calculate LCM of 72,72,12
2 | 72, 72, 12 |
2 | 36, 36, 6 |
2 | 18, 18, 3 |
3 | 9, 9, 3 |
3 | 1, 3, 3 |
1, 1, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 3 x 1 x 1 x 1 = 72
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/72
Therefore, the GCF of Fractions 33/72,67/72,17/12 is 1/72
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 72,72,12 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(72,72,12) = 12
common factors(in case of two or more numbers have common factors) = 72
GCF(72,72,12) x common factors =12 x 72 = 864
LCM(72,72,12) = ( 72 × 72 × 12 ) / 864
LCM(72,72,12) = 62208 / 864
LCM(72,72,12) = 72
