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 3,176,285, 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 | 3,176,285 | |
| -1 | -3,176,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,176,285.
Example:
1 x 3,176,285 = 3,176,285
and
-1 x -3,176,285 = 3,176,285
Notice both answers equal 3,176,285
With that explanation out of the way, let's continue. Next, we take the number 3,176,285 and divide it by 2:
3,176,285 ÷ 2 = 1,588,142.5
If the quotient is a whole number, then 2 and 1,588,142.5 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 | 3,176,285 | |
| -1 | -3,176,285 |
Now, we try dividing 3,176,285 by 3:
3,176,285 ÷ 3 = 1,058,761.6667
If the quotient is a whole number, then 3 and 1,058,761.6667 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 | 3,176,285 | |
| -1 | -3,176,285 |
Let's try dividing by 4:
3,176,285 ÷ 4 = 794,071.25
If the quotient is a whole number, then 4 and 794,071.25 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 | 3,176,285 | |
| -1 | 3,176,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 151 | 601 | 755 | 1,057 | 3,005 | 4,207 | 5,285 | 21,035 | 90,751 | 453,755 | 635,257 | 3,176,285 |
| -1 | -5 | -7 | -35 | -151 | -601 | -755 | -1,057 | -3,005 | -4,207 | -5,285 | -21,035 | -90,751 | -453,755 | -635,257 | -3,176,285 |
