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 232,512,431, 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 | 232,512,431 | |
| -1 | -232,512,431 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 232,512,431.
Example:
1 x 232,512,431 = 232,512,431
and
-1 x -232,512,431 = 232,512,431
Notice both answers equal 232,512,431
With that explanation out of the way, let's continue. Next, we take the number 232,512,431 and divide it by 2:
232,512,431 ÷ 2 = 116,256,215.5
If the quotient is a whole number, then 2 and 116,256,215.5 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 | 232,512,431 | |
| -1 | -232,512,431 |
Now, we try dividing 232,512,431 by 3:
232,512,431 ÷ 3 = 77,504,143.6667
If the quotient is a whole number, then 3 and 77,504,143.6667 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 | 232,512,431 | |
| -1 | -232,512,431 |
Let's try dividing by 4:
232,512,431 ÷ 4 = 58,128,107.75
If the quotient is a whole number, then 4 and 58,128,107.75 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 | 232,512,431 | |
| -1 | 232,512,431 |
If you did it right, you will end up with this table:
| 1 | 31 | 47 | 53 | 1,457 | 1,643 | 2,491 | 3,011 | 77,221 | 93,341 | 141,517 | 159,583 | 4,387,027 | 4,947,073 | 7,500,401 | 232,512,431 |
| -1 | -31 | -47 | -53 | -1,457 | -1,643 | -2,491 | -3,011 | -77,221 | -93,341 | -141,517 | -159,583 | -4,387,027 | -4,947,073 | -7,500,401 | -232,512,431 |
