What are fun facts on number 84?
The number 84 is interesting because it is a semiprime, meaning it is the product of two prime numbers (2 and 42). In addition, 84 is a highly composite number, having more divisors than any smaller number, with a total of 12 divisors. It is also the atomic number of polonium, a radioactive element. Furthermore, in the realm of sports, the number 84 has been worn by several famous athletes, particularly in American football.
How can you find the number of positive divisors of a natural number without listing all the divisors?
What you are trying to do is called the tau function - the number of positive divisors of a natural number, n, is written as tau(n). How to do it: Simplify your number into its prime factors. For example, 84 = 4 * 3 * 7 = (2^2) * (3^1) * (7^1). Then, make a list of all the powers from the previous step. This gives us a list of 2, 1, and 1. Add one to every number in the list. Our list is now 3, 2, and 2. Multiply all the numbers in the list together, and you're done. 3 * 2 * 2 = 12. 84 has 12 positive divisors, which is easily verified: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84.
