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 244,443,155, 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 | 244,443,155 | |
| -1 | -244,443,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 244,443,155.
Example:
1 x 244,443,155 = 244,443,155
and
-1 x -244,443,155 = 244,443,155
Notice both answers equal 244,443,155
With that explanation out of the way, let's continue. Next, we take the number 244,443,155 and divide it by 2:
244,443,155 ÷ 2 = 122,221,577.5
If the quotient is a whole number, then 2 and 122,221,577.5 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 | 244,443,155 | |
| -1 | -244,443,155 |
Now, we try dividing 244,443,155 by 3:
244,443,155 ÷ 3 = 81,481,051.6667
If the quotient is a whole number, then 3 and 81,481,051.6667 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 | 244,443,155 | |
| -1 | -244,443,155 |
Let's try dividing by 4:
244,443,155 ÷ 4 = 61,110,788.75
If the quotient is a whole number, then 4 and 61,110,788.75 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 | 244,443,155 | |
| -1 | 244,443,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 53 | 55 | 265 | 583 | 2,915 | 83,857 | 419,285 | 922,427 | 4,444,421 | 4,612,135 | 22,222,105 | 48,888,631 | 244,443,155 |
| -1 | -5 | -11 | -53 | -55 | -265 | -583 | -2,915 | -83,857 | -419,285 | -922,427 | -4,444,421 | -4,612,135 | -22,222,105 | -48,888,631 | -244,443,155 |
