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 3,155,693, 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 | 3,155,693 | |
| -1 | -3,155,693 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,155,693.
Example:
1 x 3,155,693 = 3,155,693
and
-1 x -3,155,693 = 3,155,693
Notice both answers equal 3,155,693
With that explanation out of the way, let's continue. Next, we take the number 3,155,693 and divide it by 2:
3,155,693 ÷ 2 = 1,577,846.5
If the quotient is a whole number, then 2 and 1,577,846.5 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 | 3,155,693 | |
| -1 | -3,155,693 |
Now, we try dividing 3,155,693 by 3:
3,155,693 ÷ 3 = 1,051,897.6667
If the quotient is a whole number, then 3 and 1,051,897.6667 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 | 3,155,693 | |
| -1 | -3,155,693 |
Let's try dividing by 4:
3,155,693 ÷ 4 = 788,923.25
If the quotient is a whole number, then 4 and 788,923.25 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 | 3,155,693 | |
| -1 | 3,155,693 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 37 | 173 | 493 | 629 | 1,073 | 2,941 | 5,017 | 6,401 | 18,241 | 85,289 | 108,817 | 185,629 | 3,155,693 |
| -1 | -17 | -29 | -37 | -173 | -493 | -629 | -1,073 | -2,941 | -5,017 | -6,401 | -18,241 | -85,289 | -108,817 | -185,629 | -3,155,693 |
