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 1,616,315, 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 | 1,616,315 | |
| -1 | -1,616,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,616,315.
Example:
1 x 1,616,315 = 1,616,315
and
-1 x -1,616,315 = 1,616,315
Notice both answers equal 1,616,315
With that explanation out of the way, let's continue. Next, we take the number 1,616,315 and divide it by 2:
1,616,315 ÷ 2 = 808,157.5
If the quotient is a whole number, then 2 and 808,157.5 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 | 1,616,315 | |
| -1 | -1,616,315 |
Now, we try dividing 1,616,315 by 3:
1,616,315 ÷ 3 = 538,771.6667
If the quotient is a whole number, then 3 and 538,771.6667 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 | 1,616,315 | |
| -1 | -1,616,315 |
Let's try dividing by 4:
1,616,315 ÷ 4 = 404,078.75
If the quotient is a whole number, then 4 and 404,078.75 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 | 1,616,315 | |
| -1 | 1,616,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 71 | 145 | 157 | 355 | 785 | 2,059 | 4,553 | 10,295 | 11,147 | 22,765 | 55,735 | 323,263 | 1,616,315 |
| -1 | -5 | -29 | -71 | -145 | -157 | -355 | -785 | -2,059 | -4,553 | -10,295 | -11,147 | -22,765 | -55,735 | -323,263 | -1,616,315 |
