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 244,223,551, 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 | 244,223,551 | |
| -1 | -244,223,551 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 244,223,551.
Example:
1 x 244,223,551 = 244,223,551
and
-1 x -244,223,551 = 244,223,551
Notice both answers equal 244,223,551
With that explanation out of the way, let's continue. Next, we take the number 244,223,551 and divide it by 2:
244,223,551 ÷ 2 = 122,111,775.5
If the quotient is a whole number, then 2 and 122,111,775.5 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 | 244,223,551 | |
| -1 | -244,223,551 |
Now, we try dividing 244,223,551 by 3:
244,223,551 ÷ 3 = 81,407,850.3333
If the quotient is a whole number, then 3 and 81,407,850.3333 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 | 244,223,551 | |
| -1 | -244,223,551 |
Let's try dividing by 4:
244,223,551 ÷ 4 = 61,055,887.75
If the quotient is a whole number, then 4 and 61,055,887.75 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 | 244,223,551 | |
| -1 | 244,223,551 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 193 | 2,123 | 2,509 | 8,849 | 27,599 | 97,339 | 115,037 | 1,265,407 | 1,707,857 | 18,786,427 | 22,202,141 | 244,223,551 |
| -1 | -11 | -13 | -143 | -193 | -2,123 | -2,509 | -8,849 | -27,599 | -97,339 | -115,037 | -1,265,407 | -1,707,857 | -18,786,427 | -22,202,141 | -244,223,551 |
