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 divisors of larger numbers. To find the factor combinations of the number 689,095, it is easier to work with a table - it's called factoring from the outside in.
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. Then, below that, write the numbers as a negative as well.
| 1 | 689,095 | |
| -1 | -689,095 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 689,095.
Example:
1 x 689,095 = 689,095
and
-1 x -689,095 = 689,095
Notice both answers equal 689,095
With that explanation out of the way, let's continue. Next, we take the number 689,095 and divide it by 2:
689,095 ÷ 2 = 344,547.5
If the quotient is a whole number, then 2 and 344,547.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 689,095 | |
| -1 | -689,095 |
Now, we try dividing 689,095 by 3:
689,095 ÷ 3 = 229,698.3333
If the quotient is a whole number, then 3 and 229,698.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 689,095 | |
| -1 | -689,095 |
Let's try dividing by 4:
689,095 ÷ 4 = 172,273.75
If the quotient is a whole number, then 4 and 172,273.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 689,095 | |
| -1 | 689,095 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 67 | 85 | 121 | 187 | 335 | 605 | 737 | 935 | 1,139 | 2,057 | 3,685 | 5,695 | 8,107 | 10,285 | 12,529 | 40,535 | 62,645 | 137,819 | 689,095 |
| -1 | -5 | -11 | -17 | -55 | -67 | -85 | -121 | -187 | -335 | -605 | -737 | -935 | -1,139 | -2,057 | -3,685 | -5,695 | -8,107 | -10,285 | -12,529 | -40,535 | -62,645 | -137,819 | -689,095 |
