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 622,162,073, 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 | 622,162,073 | |
| -1 | -622,162,073 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 622,162,073.
Example:
1 x 622,162,073 = 622,162,073
and
-1 x -622,162,073 = 622,162,073
Notice both answers equal 622,162,073
With that explanation out of the way, let's continue. Next, we take the number 622,162,073 and divide it by 2:
622,162,073 ÷ 2 = 311,081,036.5
If the quotient is a whole number, then 2 and 311,081,036.5 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 | 622,162,073 | |
| -1 | -622,162,073 |
Now, we try dividing 622,162,073 by 3:
622,162,073 ÷ 3 = 207,387,357.6667
If the quotient is a whole number, then 3 and 207,387,357.6667 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 | 622,162,073 | |
| -1 | -622,162,073 |
Let's try dividing by 4:
622,162,073 ÷ 4 = 155,540,518.25
If the quotient is a whole number, then 4 and 155,540,518.25 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 | 622,162,073 | |
| -1 | 622,162,073 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 137 | 221 | 1,781 | 2,329 | 20,549 | 30,277 | 267,137 | 349,333 | 2,815,213 | 4,541,329 | 36,597,769 | 47,858,621 | 622,162,073 |
| -1 | -13 | -17 | -137 | -221 | -1,781 | -2,329 | -20,549 | -30,277 | -267,137 | -349,333 | -2,815,213 | -4,541,329 | -36,597,769 | -47,858,621 | -622,162,073 |
