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 233,421,227, 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 | 233,421,227 | |
| -1 | -233,421,227 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 233,421,227.
Example:
1 x 233,421,227 = 233,421,227
and
-1 x -233,421,227 = 233,421,227
Notice both answers equal 233,421,227
With that explanation out of the way, let's continue. Next, we take the number 233,421,227 and divide it by 2:
233,421,227 ÷ 2 = 116,710,613.5
If the quotient is a whole number, then 2 and 116,710,613.5 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 | 233,421,227 | |
| -1 | -233,421,227 |
Now, we try dividing 233,421,227 by 3:
233,421,227 ÷ 3 = 77,807,075.6667
If the quotient is a whole number, then 3 and 77,807,075.6667 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 | 233,421,227 | |
| -1 | -233,421,227 |
Let's try dividing by 4:
233,421,227 ÷ 4 = 58,355,306.75
If the quotient is a whole number, then 4 and 58,355,306.75 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 | 233,421,227 | |
| -1 | 233,421,227 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 31 | 299 | 403 | 713 | 9,269 | 25,183 | 327,379 | 579,209 | 780,673 | 7,529,717 | 10,148,749 | 17,955,479 | 233,421,227 |
| -1 | -13 | -23 | -31 | -299 | -403 | -713 | -9,269 | -25,183 | -327,379 | -579,209 | -780,673 | -7,529,717 | -10,148,749 | -17,955,479 | -233,421,227 |
