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 689,188, it is easiest to start from the outside in. Here's what we mean:
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 | 689,188 |
Next, we take the number 689,188 and divide it by 2.
In this case, 689,188 ÷ 2 = 344,594
If the quotient is a whole number, then 2 and 344,594 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.
| 1 | 2 | 344,594 | 689,188 |
Now, we try dividing 689,188 by 3.
689,188 ÷ 3 = 229,729.3333
If the quotient is a whole number, then 3 and 229,729.3333 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 | 2 | 344,594 | 689,188 |
Let's try dividing by 4.
689,188 ÷ 4 = 172,297
If the quotient is a whole number, then 4 and 172,297 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 | 2 | 4 | 172,297 | 344,594 | 689,188 |
We keep dividing by the next largest number, in this case the number 5. If the quotient of 689,188 ÷ 5 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:
| 1 | 2 | 4 | 172,297 | 344,594 | 689,188 |
All of the numbers in the table above can be evenly divided into the number 689,188.
Finally, for your reference, here are all of the divisor combinations of the number 689,188:
1 x 689188
2 x 344594
4 x 172297
