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 523,400,429, 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 | 523,400,429 | |
| -1 | -523,400,429 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 523,400,429.
Example:
1 x 523,400,429 = 523,400,429
and
-1 x -523,400,429 = 523,400,429
Notice both answers equal 523,400,429
With that explanation out of the way, let's continue. Next, we take the number 523,400,429 and divide it by 2:
523,400,429 ÷ 2 = 261,700,214.5
If the quotient is a whole number, then 2 and 261,700,214.5 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 | 523,400,429 | |
| -1 | -523,400,429 |
Now, we try dividing 523,400,429 by 3:
523,400,429 ÷ 3 = 174,466,809.6667
If the quotient is a whole number, then 3 and 174,466,809.6667 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 | 523,400,429 | |
| -1 | -523,400,429 |
Let's try dividing by 4:
523,400,429 ÷ 4 = 130,850,107.25
If the quotient is a whole number, then 4 and 130,850,107.25 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 | 523,400,429 | |
| -1 | 523,400,429 |
If you did it right, you will end up with this table:
| 1 | 19 | 43 | 337 | 817 | 1,901 | 6,403 | 14,491 | 36,119 | 81,743 | 275,329 | 640,637 | 1,553,117 | 12,172,103 | 27,547,391 | 523,400,429 |
| -1 | -19 | -43 | -337 | -817 | -1,901 | -6,403 | -14,491 | -36,119 | -81,743 | -275,329 | -640,637 | -1,553,117 | -12,172,103 | -27,547,391 | -523,400,429 |
