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 123,443,441, 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 | 123,443,441 | |
| -1 | -123,443,441 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 123,443,441.
Example:
1 x 123,443,441 = 123,443,441
and
-1 x -123,443,441 = 123,443,441
Notice both answers equal 123,443,441
With that explanation out of the way, let's continue. Next, we take the number 123,443,441 and divide it by 2:
123,443,441 ÷ 2 = 61,721,720.5
If the quotient is a whole number, then 2 and 61,721,720.5 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 | 123,443,441 | |
| -1 | -123,443,441 |
Now, we try dividing 123,443,441 by 3:
123,443,441 ÷ 3 = 41,147,813.6667
If the quotient is a whole number, then 3 and 41,147,813.6667 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 | 123,443,441 | |
| -1 | -123,443,441 |
Let's try dividing by 4:
123,443,441 ÷ 4 = 30,860,860.25
If the quotient is a whole number, then 4 and 30,860,860.25 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 | 123,443,441 | |
| -1 | 123,443,441 |
If you did it right, you will end up with this table:
| 1 | 11 | 2,417 | 4,643 | 26,587 | 51,073 | 11,222,131 | 123,443,441 |
| -1 | -11 | -2,417 | -4,643 | -26,587 | -51,073 | -11,222,131 | -123,443,441 |
