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 3,169,085, 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 | 3,169,085 | |
| -1 | -3,169,085 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,169,085.
Example:
1 x 3,169,085 = 3,169,085
and
-1 x -3,169,085 = 3,169,085
Notice both answers equal 3,169,085
With that explanation out of the way, let's continue. Next, we take the number 3,169,085 and divide it by 2:
3,169,085 ÷ 2 = 1,584,542.5
If the quotient is a whole number, then 2 and 1,584,542.5 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 | 3,169,085 | |
| -1 | -3,169,085 |
Now, we try dividing 3,169,085 by 3:
3,169,085 ÷ 3 = 1,056,361.6667
If the quotient is a whole number, then 3 and 1,056,361.6667 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 | 3,169,085 | |
| -1 | -3,169,085 |
Let's try dividing by 4:
3,169,085 ÷ 4 = 792,271.25
If the quotient is a whole number, then 4 and 792,271.25 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 | 3,169,085 | |
| -1 | 3,169,085 |
If you did it right, you will end up with this table:
| 1 | 5 | 71 | 79 | 113 | 355 | 395 | 565 | 5,609 | 8,023 | 8,927 | 28,045 | 40,115 | 44,635 | 633,817 | 3,169,085 |
| -1 | -5 | -71 | -79 | -113 | -355 | -395 | -565 | -5,609 | -8,023 | -8,927 | -28,045 | -40,115 | -44,635 | -633,817 | -3,169,085 |
