What is an odd number of factors?
Perfect squares have an odd number of factors. If f is a factor of N, then so is N/f. (For example, 3 is a factor of 30, and so is 10). Thus, it seems factors come in pairs, and there should always be an even number of them. But if f = N/f, then these two factors are the same, resulting in an odd number of factors. For example, 3 is a factor of 9, and it's "mate" is also 3. So for the numbers with an odd number of factors, there is some f where f=N/f. Multiplying both sides by f, we have f^2 = N. So this happens when N is a perfect square.
What is the process of finding the factors of a big number?
For moderately large numbers, N, you can try dividing by prime numbers up to the square root of N. Each time you find a factor, f, you replace N by N/f, and continue with primes from f onwards. However, this method is impractical for really large numbers: ones that are the product of two primes, each a hundred digits long, for example. And that is why such numbers are used for encryption (codes).
What are the f-stop numbers?
F-stop numbers are the numbers used to measure aperture (the amount of light entering the camera). Because f-stop numbers are actually fractions, the larger the f-stop number, the less light is entering the camera.
Algorithm to find prime numbers below ten?
Take each number in turn, call it "n", and check whether it has any factors f, such that 1 < f < n. If it doesn't, it is a prime number.Take each number in turn, call it "n", and check whether it has any factors f, such that 1 < f < n.

What is the sub set of Fibonacci primes?
Fibonacci primes are Fibonacci numbers that are also prime numbers. The Fibonacci sequence, defined as F(0) = 0, F(1) = 1, and F(n) = F(n-1) + F(n-2) for n ≥ 2, produces a series of numbers. Among these, the Fibonacci primes include numbers like 2, 3, 5, 13, and 89, which are prime and appear within the Fibonacci sequence. Not all Fibonacci numbers are prime, making Fibonacci primes a specific subset of both prime numbers and Fibonacci numbers.
What are the numbers on a diaphragm?
The numbers on a diaphragm represent the aperture or f-stop settings available on the lens. These numbers control the size of the lens opening, with lower numbers (e.g. f/2.8) indicating a larger opening for more light to enter, and higher numbers (e.g. f/16) indicating a smaller opening for less light.
If d is the number of distinct prime factors of 12 and f is the number of positive factors of 12 what is the sum of d and f?
