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 411,330,227, 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 | 411,330,227 | |
| -1 | -411,330,227 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 411,330,227.
Example:
1 x 411,330,227 = 411,330,227
and
-1 x -411,330,227 = 411,330,227
Notice both answers equal 411,330,227
With that explanation out of the way, let's continue. Next, we take the number 411,330,227 and divide it by 2:
411,330,227 ÷ 2 = 205,665,113.5
If the quotient is a whole number, then 2 and 205,665,113.5 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 | 411,330,227 | |
| -1 | -411,330,227 |
Now, we try dividing 411,330,227 by 3:
411,330,227 ÷ 3 = 137,110,075.6667
If the quotient is a whole number, then 3 and 137,110,075.6667 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 | 411,330,227 | |
| -1 | -411,330,227 |
Let's try dividing by 4:
411,330,227 ÷ 4 = 102,832,556.75
If the quotient is a whole number, then 4 and 102,832,556.75 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 | 411,330,227 | |
| -1 | 411,330,227 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 31 | 77 | 217 | 341 | 2,387 | 172,321 | 1,206,247 | 1,895,531 | 5,341,951 | 13,268,717 | 37,393,657 | 58,761,461 | 411,330,227 |
| -1 | -7 | -11 | -31 | -77 | -217 | -341 | -2,387 | -172,321 | -1,206,247 | -1,895,531 | -5,341,951 | -13,268,717 | -37,393,657 | -58,761,461 | -411,330,227 |
