• Mar 26, 2020 · A prime number is a whole number greater than 1, which is evenly divisible only by itself and the number 1. The ancient Greek mathematicians did a comprehensive study on prime numbers and their properties.
• A prime number is only divisible by 1 and itself. If a number has more than two factors it is called a composite number. For example, 19 is a prime number. It can only be divided by 1 and 19. 9 is ...

• Number of odd factors will be all possible combinations of powers of 3 and 5 (excluding any power of 2) . Hence number of odd factors = (1+1)(1+1) = 4 By manually checking, these factors are 1, 3, 7 and 21. Number of even factors = total no. of factors - no. of even factors
If the remainder is 3, then the number n is divisible by 3, and can not be prime. So if n is prime, then the remainder r is either . 1 (and n = 6q + 1 is one more than a multiple of six), or ; 5 (and n = 6q + 5 = 6(q+1) - 1 is one less than a multiple of six).

C++ Example - C++ Program to Print Triangle of Stars.C++ Program To Print Pattern (Triangle) More generally, no Fibonaci number other than 1 can be multiply perfect, and no ratio of two Fibonacci numbers can be perfect. Prime divisors. With the exceptions of 1, 8 and 144 (F 1 = F 2, F 6 and F 12) every Fibonacci number has a prime factor that is not a factor of any smaller Fibonacci number (Carmichael's theorem).

Write a program to find the given number is Armstrong number or not? Write a program to convert binary to decimal number.
Definition A twin prime is a prime number that has a prime gap of two. In other words, to qualify as a twin prime, the prime number must be either 2 less or 2 more than another prime number (which by definition would mean that it, too, is a twin prime)?for example, the twin prime pair (41, 43). The fraction can’t be reduced, and so the two numbers are relatively prime. The beauty of using prime factorization is that you can be sure that the fraction’s reduction possibilities are exhausted — you haven’t missed anything. You can leave the fraction in this factored form or go back to the simpler 100/243. It depends on your ...
