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 226,732,121, 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 | 226,732,121 | |
| -1 | -226,732,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 226,732,121.
Example:
1 x 226,732,121 = 226,732,121
and
-1 x -226,732,121 = 226,732,121
Notice both answers equal 226,732,121
With that explanation out of the way, let's continue. Next, we take the number 226,732,121 and divide it by 2:
226,732,121 ÷ 2 = 113,366,060.5
If the quotient is a whole number, then 2 and 113,366,060.5 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 | 226,732,121 | |
| -1 | -226,732,121 |
Now, we try dividing 226,732,121 by 3:
226,732,121 ÷ 3 = 75,577,373.6667
If the quotient is a whole number, then 3 and 75,577,373.6667 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 | 226,732,121 | |
| -1 | -226,732,121 |
Let's try dividing by 4:
226,732,121 ÷ 4 = 56,683,030.25
If the quotient is a whole number, then 4 and 56,683,030.25 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 | 226,732,121 | |
| -1 | 226,732,121 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 29 | 77 | 203 | 319 | 2,233 | 101,537 | 710,759 | 1,116,907 | 2,944,573 | 7,818,349 | 20,612,011 | 32,390,303 | 226,732,121 |
| -1 | -7 | -11 | -29 | -77 | -203 | -319 | -2,233 | -101,537 | -710,759 | -1,116,907 | -2,944,573 | -7,818,349 | -20,612,011 | -32,390,303 | -226,732,121 |
