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.

What is the HCF 16 and 24?
Since 12 is a factor of 24, it is automatically the GCF.
What is the HCF 8 of and 24?
8 is the highest common factor of 8 & 24. 8 * 1 = 8 and 8 * 3 = 24.
What is the HCF of 24 40 72?
The GCF is 8.
What is he hcf of 24 and 36?
The hcf is 12
What is the HCF 0f 8 12 and 24?
The GCF is 2.
What is HCF of 24 and 12?
12
What is the HCf of 2436?
If you mean 24 and 36 then the HCF is 12
What is the HCF of 12 24 and 36?
It is 12
What is the HCF of 8 24 and 32?
8
Hcf of 24 and 32?
It is 8
What two numbers have an LCM of 24 and an HCF of 2?
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.
What is HCF of 24 and 84?
It is: 12
