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 660,569, 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 | 660,569 | |
| -1 | -660,569 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 660,569.
Example:
1 x 660,569 = 660,569
and
-1 x -660,569 = 660,569
Notice both answers equal 660,569
With that explanation out of the way, let's continue. Next, we take the number 660,569 and divide it by 2:
660,569 ÷ 2 = 330,284.5
If the quotient is a whole number, then 2 and 330,284.5 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 | 660,569 | |
| -1 | -660,569 |
Now, we try dividing 660,569 by 3:
660,569 ÷ 3 = 220,189.6667
If the quotient is a whole number, then 3 and 220,189.6667 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 | 660,569 | |
| -1 | -660,569 |
Let's try dividing by 4:
660,569 ÷ 4 = 165,142.25
If the quotient is a whole number, then 4 and 165,142.25 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 | 660,569 | |
| -1 | 660,569 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 17 | 49 | 61 | 91 | 119 | 221 | 427 | 637 | 793 | 833 | 1,037 | 1,547 | 2,989 | 5,551 | 7,259 | 10,829 | 13,481 | 38,857 | 50,813 | 94,367 | 660,569 |
| -1 | -7 | -13 | -17 | -49 | -61 | -91 | -119 | -221 | -427 | -637 | -793 | -833 | -1,037 | -1,547 | -2,989 | -5,551 | -7,259 | -10,829 | -13,481 | -38,857 | -50,813 | -94,367 | -660,569 |
