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 622,773,217, 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 | 622,773,217 | |
| -1 | -622,773,217 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 622,773,217.
Example:
1 x 622,773,217 = 622,773,217
and
-1 x -622,773,217 = 622,773,217
Notice both answers equal 622,773,217
With that explanation out of the way, let's continue. Next, we take the number 622,773,217 and divide it by 2:
622,773,217 ÷ 2 = 311,386,608.5
If the quotient is a whole number, then 2 and 311,386,608.5 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 | 622,773,217 | |
| -1 | -622,773,217 |
Now, we try dividing 622,773,217 by 3:
622,773,217 ÷ 3 = 207,591,072.3333
If the quotient is a whole number, then 3 and 207,591,072.3333 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 | 622,773,217 | |
| -1 | -622,773,217 |
Let's try dividing by 4:
622,773,217 ÷ 4 = 155,693,304.25
If the quotient is a whole number, then 4 and 155,693,304.25 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 | 622,773,217 | |
| -1 | 622,773,217 |
If you did it right, you will end up with this table:
| 1 | 11 | 61 | 263 | 671 | 2,893 | 3,529 | 16,043 | 38,819 | 176,473 | 215,269 | 928,127 | 2,367,959 | 10,209,397 | 56,615,747 | 622,773,217 |
| -1 | -11 | -61 | -263 | -671 | -2,893 | -3,529 | -16,043 | -38,819 | -176,473 | -215,269 | -928,127 | -2,367,959 | -10,209,397 | -56,615,747 | -622,773,217 |
