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 235,404,403, 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 | 235,404,403 | |
| -1 | -235,404,403 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 235,404,403.
Example:
1 x 235,404,403 = 235,404,403
and
-1 x -235,404,403 = 235,404,403
Notice both answers equal 235,404,403
With that explanation out of the way, let's continue. Next, we take the number 235,404,403 and divide it by 2:
235,404,403 ÷ 2 = 117,702,201.5
If the quotient is a whole number, then 2 and 117,702,201.5 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 | 235,404,403 | |
| -1 | -235,404,403 |
Now, we try dividing 235,404,403 by 3:
235,404,403 ÷ 3 = 78,468,134.3333
If the quotient is a whole number, then 3 and 78,468,134.3333 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 | 235,404,403 | |
| -1 | -235,404,403 |
Let's try dividing by 4:
235,404,403 ÷ 4 = 58,851,100.75
If the quotient is a whole number, then 4 and 58,851,100.75 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 | 235,404,403 | |
| -1 | 235,404,403 |
If you did it right, you will end up with this table:
| 1 | 13 | 43 | 373 | 559 | 1,129 | 4,849 | 14,677 | 16,039 | 48,547 | 208,507 | 421,117 | 631,111 | 5,474,521 | 18,108,031 | 235,404,403 |
| -1 | -13 | -43 | -373 | -559 | -1,129 | -4,849 | -14,677 | -16,039 | -48,547 | -208,507 | -421,117 | -631,111 | -5,474,521 | -18,108,031 | -235,404,403 |
