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 244,025,551, 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 | 244,025,551 | |
| -1 | -244,025,551 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 244,025,551.
Example:
1 x 244,025,551 = 244,025,551
and
-1 x -244,025,551 = 244,025,551
Notice both answers equal 244,025,551
With that explanation out of the way, let's continue. Next, we take the number 244,025,551 and divide it by 2:
244,025,551 ÷ 2 = 122,012,775.5
If the quotient is a whole number, then 2 and 122,012,775.5 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 | 244,025,551 | |
| -1 | -244,025,551 |
Now, we try dividing 244,025,551 by 3:
244,025,551 ÷ 3 = 81,341,850.3333
If the quotient is a whole number, then 3 and 81,341,850.3333 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 | 244,025,551 | |
| -1 | -244,025,551 |
Let's try dividing by 4:
244,025,551 ÷ 4 = 61,006,387.75
If the quotient is a whole number, then 4 and 61,006,387.75 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 | 244,025,551 | |
| -1 | 244,025,551 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 47 | 77 | 329 | 517 | 3,619 | 67,429 | 472,003 | 741,719 | 3,169,163 | 5,192,033 | 22,184,141 | 34,860,793 | 244,025,551 |
| -1 | -7 | -11 | -47 | -77 | -329 | -517 | -3,619 | -67,429 | -472,003 | -741,719 | -3,169,163 | -5,192,033 | -22,184,141 | -34,860,793 | -244,025,551 |
