- For example, choose 72. However, it can also be treated as a variable.

- 72 is broken down into 2 and 36; 2, 6 and 6; and finally: 2, 2, 3, 2, 3, which is equivalent to 2 3 *3 2 .

- In the example 2 3 and 3 2 , the exponents are 3 and 2 – adding one to each number gives 4 and 3.

- 4 x 3 = 12. 72 has 12 factors – 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36 and 72.
For example
7540
- Factorize into primes – 2 2 5(29)(13). Because x 1 = x, 29, 13, and 5 all have exponents of 1.
- Add 1 to the exponent. 3, 2, 2, 2.
- Get the adjusted exponent total. 7540 has 24 factors.
15802
- Factorize to prime – 2(7901).
- Adjust the exponent – 2, 2.
- Add. The number 15802 has four factors – 1, 2, 7901, 15802. 7901 is a prime number.
Advice
- The reason for adding one to each exponent is because the power of a number is zero. That is, for 2 3 , it is possible to decompose into four power combinations: 2 0 , 2 1 , 2 2 and 2 3 . You can multiply 2 0 by 72 and still get 72 by x 0 = 1 (with 0 0 being the special exception – it’s an unspecified case)

In conclusion, determining the number of factors in a given number may seem like a daunting task, but utilizing certain techniques and mathematical rules can greatly simplify the process. By breaking the number down into its prime factors, one can determine the different combinations of factors and easily calculate the total number. Additionally, understanding the properties of factors, such as their pairing and the inclusion of the number itself and unity, can further aid in locating all the factors. Moreover, the squared factor rule and the concept of perfect square numbers can provide valuable insights into the factorization process. As with any mathematical concept, practice and familiarity with number properties are key to mastering the skill of calculating the number of factors in a number.
