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 403,203,031, 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 | 403,203,031 | |
| -1 | -403,203,031 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 403,203,031.
Example:
1 x 403,203,031 = 403,203,031
and
-1 x -403,203,031 = 403,203,031
Notice both answers equal 403,203,031
With that explanation out of the way, let's continue. Next, we take the number 403,203,031 and divide it by 2:
403,203,031 ÷ 2 = 201,601,515.5
If the quotient is a whole number, then 2 and 201,601,515.5 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 | 403,203,031 | |
| -1 | -403,203,031 |
Now, we try dividing 403,203,031 by 3:
403,203,031 ÷ 3 = 134,401,010.3333
If the quotient is a whole number, then 3 and 134,401,010.3333 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 | 403,203,031 | |
| -1 | -403,203,031 |
Let's try dividing by 4:
403,203,031 ÷ 4 = 100,800,757.75
If the quotient is a whole number, then 4 and 100,800,757.75 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 | 403,203,031 | |
| -1 | 403,203,031 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 1,789 | 2,927 | 12,523 | 19,679 | 20,489 | 32,197 | 137,753 | 225,379 | 5,236,403 | 36,654,821 | 57,600,433 | 403,203,031 |
| -1 | -7 | -11 | -77 | -1,789 | -2,927 | -12,523 | -19,679 | -20,489 | -32,197 | -137,753 | -225,379 | -5,236,403 | -36,654,821 | -57,600,433 | -403,203,031 |
