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 16,413,265, 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 | 16,413,265 | |
| -1 | -16,413,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,413,265.
Example:
1 x 16,413,265 = 16,413,265
and
-1 x -16,413,265 = 16,413,265
Notice both answers equal 16,413,265
With that explanation out of the way, let's continue. Next, we take the number 16,413,265 and divide it by 2:
16,413,265 ÷ 2 = 8,206,632.5
If the quotient is a whole number, then 2 and 8,206,632.5 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 | 16,413,265 | |
| -1 | -16,413,265 |
Now, we try dividing 16,413,265 by 3:
16,413,265 ÷ 3 = 5,471,088.3333
If the quotient is a whole number, then 3 and 5,471,088.3333 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 | 16,413,265 | |
| -1 | -16,413,265 |
Let's try dividing by 4:
16,413,265 ÷ 4 = 4,103,316.25
If the quotient is a whole number, then 4 and 4,103,316.25 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 | 16,413,265 | |
| -1 | 16,413,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 107 | 535 | 1,177 | 2,789 | 5,885 | 13,945 | 30,679 | 153,395 | 298,423 | 1,492,115 | 3,282,653 | 16,413,265 |
| -1 | -5 | -11 | -55 | -107 | -535 | -1,177 | -2,789 | -5,885 | -13,945 | -30,679 | -153,395 | -298,423 | -1,492,115 | -3,282,653 | -16,413,265 |
