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 880,187, 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 | 880,187 | |
| -1 | -880,187 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 880,187.
Example:
1 x 880,187 = 880,187
and
-1 x -880,187 = 880,187
Notice both answers equal 880,187
With that explanation out of the way, let's continue. Next, we take the number 880,187 and divide it by 2:
880,187 ÷ 2 = 440,093.5
If the quotient is a whole number, then 2 and 440,093.5 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 | 880,187 | |
| -1 | -880,187 |
Now, we try dividing 880,187 by 3:
880,187 ÷ 3 = 293,395.6667
If the quotient is a whole number, then 3 and 293,395.6667 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 | 880,187 | |
| -1 | -880,187 |
Let's try dividing by 4:
880,187 ÷ 4 = 220,046.75
If the quotient is a whole number, then 4 and 220,046.75 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 | 880,187 | |
| -1 | 880,187 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 23 | 49 | 71 | 77 | 161 | 253 | 497 | 539 | 781 | 1,127 | 1,633 | 1,771 | 3,479 | 5,467 | 11,431 | 12,397 | 17,963 | 38,269 | 80,017 | 125,741 | 880,187 |
| -1 | -7 | -11 | -23 | -49 | -71 | -77 | -161 | -253 | -497 | -539 | -781 | -1,127 | -1,633 | -1,771 | -3,479 | -5,467 | -11,431 | -12,397 | -17,963 | -38,269 | -80,017 | -125,741 | -880,187 |
