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 233,152,403, 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 | 233,152,403 | |
| -1 | -233,152,403 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 233,152,403.
Example:
1 x 233,152,403 = 233,152,403
and
-1 x -233,152,403 = 233,152,403
Notice both answers equal 233,152,403
With that explanation out of the way, let's continue. Next, we take the number 233,152,403 and divide it by 2:
233,152,403 ÷ 2 = 116,576,201.5
If the quotient is a whole number, then 2 and 116,576,201.5 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 | 233,152,403 | |
| -1 | -233,152,403 |
Now, we try dividing 233,152,403 by 3:
233,152,403 ÷ 3 = 77,717,467.6667
If the quotient is a whole number, then 3 and 77,717,467.6667 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 | 233,152,403 | |
| -1 | -233,152,403 |
Let's try dividing by 4:
233,152,403 ÷ 4 = 58,288,100.75
If the quotient is a whole number, then 4 and 58,288,100.75 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 | 233,152,403 | |
| -1 | 233,152,403 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 253 | 953 | 967 | 10,483 | 10,637 | 21,919 | 22,241 | 241,109 | 244,651 | 921,551 | 10,137,061 | 21,195,673 | 233,152,403 |
| -1 | -11 | -23 | -253 | -953 | -967 | -10,483 | -10,637 | -21,919 | -22,241 | -241,109 | -244,651 | -921,551 | -10,137,061 | -21,195,673 | -233,152,403 |
