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 3,627,239, 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 | 3,627,239 | |
| -1 | -3,627,239 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,627,239.
Example:
1 x 3,627,239 = 3,627,239
and
-1 x -3,627,239 = 3,627,239
Notice both answers equal 3,627,239
With that explanation out of the way, let's continue. Next, we take the number 3,627,239 and divide it by 2:
3,627,239 ÷ 2 = 1,813,619.5
If the quotient is a whole number, then 2 and 1,813,619.5 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 | 3,627,239 | |
| -1 | -3,627,239 |
Now, we try dividing 3,627,239 by 3:
3,627,239 ÷ 3 = 1,209,079.6667
If the quotient is a whole number, then 3 and 1,209,079.6667 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 | 3,627,239 | |
| -1 | -3,627,239 |
Let's try dividing by 4:
3,627,239 ÷ 4 = 906,809.75
If the quotient is a whole number, then 4 and 906,809.75 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 | 3,627,239 | |
| -1 | 3,627,239 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 17 | 77 | 119 | 163 | 187 | 289 | 1,141 | 1,309 | 1,793 | 2,023 | 2,771 | 3,179 | 12,551 | 19,397 | 22,253 | 30,481 | 47,107 | 213,367 | 329,749 | 518,177 | 3,627,239 |
| -1 | -7 | -11 | -17 | -77 | -119 | -163 | -187 | -289 | -1,141 | -1,309 | -1,793 | -2,023 | -2,771 | -3,179 | -12,551 | -19,397 | -22,253 | -30,481 | -47,107 | -213,367 | -329,749 | -518,177 | -3,627,239 |
