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 244,553,155, 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 | 244,553,155 | |
| -1 | -244,553,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 244,553,155.
Example:
1 x 244,553,155 = 244,553,155
and
-1 x -244,553,155 = 244,553,155
Notice both answers equal 244,553,155
With that explanation out of the way, let's continue. Next, we take the number 244,553,155 and divide it by 2:
244,553,155 ÷ 2 = 122,276,577.5
If the quotient is a whole number, then 2 and 122,276,577.5 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 | 244,553,155 | |
| -1 | -244,553,155 |
Now, we try dividing 244,553,155 by 3:
244,553,155 ÷ 3 = 81,517,718.3333
If the quotient is a whole number, then 3 and 81,517,718.3333 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 | 244,553,155 | |
| -1 | -244,553,155 |
Let's try dividing by 4:
244,553,155 ÷ 4 = 61,138,288.75
If the quotient is a whole number, then 4 and 61,138,288.75 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 | 244,553,155 | |
| -1 | 244,553,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 635,203 | 3,176,015 | 4,446,421 | 6,987,233 | 22,232,105 | 34,936,165 | 48,910,631 | 244,553,155 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -635,203 | -3,176,015 | -4,446,421 | -6,987,233 | -22,232,105 | -34,936,165 | -48,910,631 | -244,553,155 |
