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 226,242,545, 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 | 226,242,545 | |
| -1 | -226,242,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 226,242,545.
Example:
1 x 226,242,545 = 226,242,545
and
-1 x -226,242,545 = 226,242,545
Notice both answers equal 226,242,545
With that explanation out of the way, let's continue. Next, we take the number 226,242,545 and divide it by 2:
226,242,545 ÷ 2 = 113,121,272.5
If the quotient is a whole number, then 2 and 113,121,272.5 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 | 226,242,545 | |
| -1 | -226,242,545 |
Now, we try dividing 226,242,545 by 3:
226,242,545 ÷ 3 = 75,414,181.6667
If the quotient is a whole number, then 3 and 75,414,181.6667 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 | 226,242,545 | |
| -1 | -226,242,545 |
Let's try dividing by 4:
226,242,545 ÷ 4 = 56,560,636.25
If the quotient is a whole number, then 4 and 56,560,636.25 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 | 226,242,545 | |
| -1 | 226,242,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 151 | 755 | 2,567 | 12,835 | 17,627 | 88,135 | 299,659 | 1,498,295 | 2,661,677 | 13,308,385 | 45,248,509 | 226,242,545 |
| -1 | -5 | -17 | -85 | -151 | -755 | -2,567 | -12,835 | -17,627 | -88,135 | -299,659 | -1,498,295 | -2,661,677 | -13,308,385 | -45,248,509 | -226,242,545 |
