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 3,116,659, 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 | 3,116,659 | |
| -1 | -3,116,659 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,116,659.
Example:
1 x 3,116,659 = 3,116,659
and
-1 x -3,116,659 = 3,116,659
Notice both answers equal 3,116,659
With that explanation out of the way, let's continue. Next, we take the number 3,116,659 and divide it by 2:
3,116,659 ÷ 2 = 1,558,329.5
If the quotient is a whole number, then 2 and 1,558,329.5 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 | 3,116,659 | |
| -1 | -3,116,659 |
Now, we try dividing 3,116,659 by 3:
3,116,659 ÷ 3 = 1,038,886.3333
If the quotient is a whole number, then 3 and 1,038,886.3333 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 | 3,116,659 | |
| -1 | -3,116,659 |
Let's try dividing by 4:
3,116,659 ÷ 4 = 779,164.75
If the quotient is a whole number, then 4 and 779,164.75 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 | 3,116,659 | |
| -1 | 3,116,659 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 29 | 91 | 203 | 377 | 1,181 | 2,639 | 8,267 | 15,353 | 34,249 | 107,471 | 239,743 | 445,237 | 3,116,659 |
| -1 | -7 | -13 | -29 | -91 | -203 | -377 | -1,181 | -2,639 | -8,267 | -15,353 | -34,249 | -107,471 | -239,743 | -445,237 | -3,116,659 |
