The HCF of 24,84 is 12.
Lets's calculate GCF of 24,84
2 | 24, 84 |
2 | 12, 42 |
3 | 6, 21 |
2, 7 |
∴ So the GCF of the given numbers is 2 x 2 x 3 = 12
Now, list down the factors of 24
:1,2,3,4,6,8,12,24
Now, list down the factors of 84
:1,2,3,4,6,7,12,14,21,28,42,84
Greatest Common Factor
We found the factors 24,84 . The biggest common factor number is the GCF number.
So the greatest common factor 24,84 is 12.
Lets's calculate LCM of 108,678
2 | 108, 678 |
3 | 54, 339 |
18, 113 |
∴ So the LCM of the given numbers is 2 x 3 x 18 x 113 = 12204
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 12/12204
Therefore, the GCF of Fractions 24/108,84/678 is 12/12204
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 108,678 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(108,678) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(108,678) x common factors =6 x 1 = 6
LCM(108,678) = ( 108 × 678 ) / 6
LCM(108,678) = 73224 / 6
LCM(108,678) = 12204
