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 3,223,415, 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 | 3,223,415 | |
| -1 | -3,223,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,223,415.
Example:
1 x 3,223,415 = 3,223,415
and
-1 x -3,223,415 = 3,223,415
Notice both answers equal 3,223,415
With that explanation out of the way, let's continue. Next, we take the number 3,223,415 and divide it by 2:
3,223,415 ÷ 2 = 1,611,707.5
If the quotient is a whole number, then 2 and 1,611,707.5 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 | 3,223,415 | |
| -1 | -3,223,415 |
Now, we try dividing 3,223,415 by 3:
3,223,415 ÷ 3 = 1,074,471.6667
If the quotient is a whole number, then 3 and 1,074,471.6667 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 | 3,223,415 | |
| -1 | -3,223,415 |
Let's try dividing by 4:
3,223,415 ÷ 4 = 805,853.75
If the quotient is a whole number, then 4 and 805,853.75 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 | 3,223,415 | |
| -1 | 3,223,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 101 | 491 | 505 | 1,313 | 2,455 | 6,383 | 6,565 | 31,915 | 49,591 | 247,955 | 644,683 | 3,223,415 |
| -1 | -5 | -13 | -65 | -101 | -491 | -505 | -1,313 | -2,455 | -6,383 | -6,565 | -31,915 | -49,591 | -247,955 | -644,683 | -3,223,415 |
