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 403,032,413, 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 | 403,032,413 | |
| -1 | -403,032,413 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 403,032,413.
Example:
1 x 403,032,413 = 403,032,413
and
-1 x -403,032,413 = 403,032,413
Notice both answers equal 403,032,413
With that explanation out of the way, let's continue. Next, we take the number 403,032,413 and divide it by 2:
403,032,413 ÷ 2 = 201,516,206.5
If the quotient is a whole number, then 2 and 201,516,206.5 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 | 403,032,413 | |
| -1 | -403,032,413 |
Now, we try dividing 403,032,413 by 3:
403,032,413 ÷ 3 = 134,344,137.6667
If the quotient is a whole number, then 3 and 134,344,137.6667 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 | 403,032,413 | |
| -1 | -403,032,413 |
Let's try dividing by 4:
403,032,413 ÷ 4 = 100,758,103.25
If the quotient is a whole number, then 4 and 100,758,103.25 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 | 403,032,413 | |
| -1 | 403,032,413 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 457 | 3,199 | 7,411 | 7,769 | 51,877 | 54,383 | 125,987 | 881,909 | 3,386,827 | 23,707,789 | 57,576,059 | 403,032,413 |
| -1 | -7 | -17 | -119 | -457 | -3,199 | -7,411 | -7,769 | -51,877 | -54,383 | -125,987 | -881,909 | -3,386,827 | -23,707,789 | -57,576,059 | -403,032,413 |
