Q: What are the factors or divisors of the number 789?

 A: 1, 3, 263, 789

How do I find the factors or divisors of the number 789?

Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the factors of larger numbers. To find the factors of the number 789, it is easiest to start from the outside in. Here's what we mean:

Outside in Factoring

We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table.

1 789

Next, we take the number 789 and divide it by 2.

In this case, 2 ÷ 789 = 394.5

If the quotient is a whole number, then 2 and 394.5 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 789

Now, we try dividing 789 by 3.

789 ÷ 3 = 263

If the quotient is a whole number, then 3 and 263 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Here is what our table should look like at this step:

1 3 263 789

Let's try dividing by 4.

789 ÷ 4 = 197.25

If the quotient is a whole number, then 4 and 197.25 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Here is what our table should look like at this step:

1 3 263 789

We keep dividing by the next largest number, in this case the number 5. If the quotient of 5 ÷ 789 is a whole number, then 5 and your quotient are factors of the number.


Keep dividing by the next highest number until you cannot divide anymore.


What you will end up with is this table:

13263789

All of the numbers in the table above can be evenly divided into the number 789.

Finally, for your reference, here are all of the divisor combinations of the number 789:

1 x 789
3 x 263
