First factor each of the 3 numbers into primes:
8= 2 x 2 x 2
12 = 2 x 2 x 3
24 = 2 x 2 x 2 x 3
Next, determine what set of factors is common to all:
2 x 2 fits the bill.
The highest common factor of a set of numbers is the multiple of the prime factors common to all, so 2 x 2 = 4 is the HCF of 8, 12, 24.
The GCF is 8.
8
HCF = 8.24 = 8 x 388 = 8 x 11
The GCF is 2.
The Highest Common Factor (HCF) of 15 and 24 is 3. To find the HCF, you can list the factors of each number and identify the largest factor they have in common. The factors of 15 are 1, 3, 5, and 15. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The largest factor they have in common is 3, making it the HCF.
Since 12 is a factor of 24, it is automatically the GCF.
The Highest Common Factor (HCF) of 8 and 24 is 8. To find the HCF, you need to determine the largest number that divides both 8 and 24 without leaving a remainder. In this case, 8 is the largest number that divides both 8 and 24 evenly, making it the HCF.
The GCF is 8.
The GCF is 2.
The hcf is 12
LCM is least common multiple, so start by factoring 24. 24's factors are: 1, 2, 3, 4, 6, 8, 12, and 24. So two of these numbers have to have a HCF (or highest common factor) of 2 to be the answer. You can rule out 1 and 3 because 2 isn't a factor. Then start listing out the multiples. Remember that 24 has to be the lowest multiple the two numbers have in common. 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24 4, 8, 12, 16, 20, 24 6, 12, 18, 24 8, 16, 24 12, 24 24 6 and 8 OR 8 and 12 OR 12 and 24 are the two here whose least common multiple is 24. But 6 and 8 are the only pair whose HCF is 2.
12
If you mean 24 and 36 then the HCF is 12
It is 12
It is 8
It is: 12
