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 622,351,169, 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 | 622,351,169 | |
| -1 | -622,351,169 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 622,351,169.
Example:
1 x 622,351,169 = 622,351,169
and
-1 x -622,351,169 = 622,351,169
Notice both answers equal 622,351,169
With that explanation out of the way, let's continue. Next, we take the number 622,351,169 and divide it by 2:
622,351,169 ÷ 2 = 311,175,584.5
If the quotient is a whole number, then 2 and 311,175,584.5 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 | 622,351,169 | |
| -1 | -622,351,169 |
Now, we try dividing 622,351,169 by 3:
622,351,169 ÷ 3 = 207,450,389.6667
If the quotient is a whole number, then 3 and 207,450,389.6667 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 | 622,351,169 | |
| -1 | -622,351,169 |
Let's try dividing by 4:
622,351,169 ÷ 4 = 155,587,792.25
If the quotient is a whole number, then 4 and 155,587,792.25 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 | 622,351,169 | |
| -1 | 622,351,169 |
If you did it right, you will end up with this table:
| 1 | 11 | 43 | 409 | 473 | 3,217 | 4,499 | 17,587 | 35,387 | 138,331 | 193,457 | 1,315,753 | 1,521,641 | 14,473,283 | 56,577,379 | 622,351,169 |
| -1 | -11 | -43 | -409 | -473 | -3,217 | -4,499 | -17,587 | -35,387 | -138,331 | -193,457 | -1,315,753 | -1,521,641 | -14,473,283 | -56,577,379 | -622,351,169 |
