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 423,131,303, 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 | 423,131,303 | |
| -1 | -423,131,303 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 423,131,303.
Example:
1 x 423,131,303 = 423,131,303
and
-1 x -423,131,303 = 423,131,303
Notice both answers equal 423,131,303
With that explanation out of the way, let's continue. Next, we take the number 423,131,303 and divide it by 2:
423,131,303 ÷ 2 = 211,565,651.5
If the quotient is a whole number, then 2 and 211,565,651.5 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 | 423,131,303 | |
| -1 | -423,131,303 |
Now, we try dividing 423,131,303 by 3:
423,131,303 ÷ 3 = 141,043,767.6667
If the quotient is a whole number, then 3 and 141,043,767.6667 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 | 423,131,303 | |
| -1 | -423,131,303 |
Let's try dividing by 4:
423,131,303 ÷ 4 = 105,782,825.75
If the quotient is a whole number, then 4 and 105,782,825.75 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 | 423,131,303 | |
| -1 | 423,131,303 |
If you did it right, you will end up with this table:
| 1 | 7 | 59 | 413 | 547 | 1,873 | 3,829 | 13,111 | 32,273 | 110,507 | 225,911 | 773,549 | 1,024,531 | 7,171,717 | 60,447,329 | 423,131,303 |
| -1 | -7 | -59 | -413 | -547 | -1,873 | -3,829 | -13,111 | -32,273 | -110,507 | -225,911 | -773,549 | -1,024,531 | -7,171,717 | -60,447,329 | -423,131,303 |
