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 622,366,055, 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 | 622,366,055 | |
| -1 | -622,366,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 622,366,055.
Example:
1 x 622,366,055 = 622,366,055
and
-1 x -622,366,055 = 622,366,055
Notice both answers equal 622,366,055
With that explanation out of the way, let's continue. Next, we take the number 622,366,055 and divide it by 2:
622,366,055 ÷ 2 = 311,183,027.5
If the quotient is a whole number, then 2 and 311,183,027.5 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 | 622,366,055 | |
| -1 | -622,366,055 |
Now, we try dividing 622,366,055 by 3:
622,366,055 ÷ 3 = 207,455,351.6667
If the quotient is a whole number, then 3 and 207,455,351.6667 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 | 622,366,055 | |
| -1 | -622,366,055 |
Let's try dividing by 4:
622,366,055 ÷ 4 = 155,591,513.75
If the quotient is a whole number, then 4 and 155,591,513.75 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 | 622,366,055 | |
| -1 | 622,366,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 157 | 433 | 785 | 1,831 | 2,165 | 9,155 | 67,981 | 287,467 | 339,905 | 792,823 | 1,437,335 | 3,964,115 | 124,473,211 | 622,366,055 |
| -1 | -5 | -157 | -433 | -785 | -1,831 | -2,165 | -9,155 | -67,981 | -287,467 | -339,905 | -792,823 | -1,437,335 | -3,964,115 | -124,473,211 | -622,366,055 |
