## How do you find the factors of a number on a TI-84?

**What is the common factors of 20?**

The number 1 is the smallest factor of every number. Every number will have a minimum of two factors, 1 and the number itself. A number that has only two factors, 1 and the number itself, is called a prime number.

**What is the smallest factor of any number?**

If a number’s digits total a number that’s divisible by 3, the number itself is divisible by 3, i.e. 3 is a factor. If a number ends with a 0 or a 5, it’s divisible by 5, i.e. 5 is a factor. If a number is divisible twice by 2, it’s divisible by 4, i.e. 4 is a factor.

To calculate the factors of large numbers, divide the numbers with the least prime number, i.e. 2. If the number is not divisible by 2, move to the next prime numbers, i.e. 3 and so on until 1 is reached. Below is an example to find the factors of a large number.

**Can you factor Trinomials on a TI-84?**

To factor on a TI-84, you can use the Equation Solver function. To access it, press the MATH button on your calculator, then hit the up arrow to scroll directly to the bottom of the list. Press ENTER and input the equation. You can also add a custom program to your calculator to more easily factor polynomials.
