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 623,052,031, 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 | 623,052,031 | |
| -1 | -623,052,031 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 623,052,031.
Example:
1 x 623,052,031 = 623,052,031
and
-1 x -623,052,031 = 623,052,031
Notice both answers equal 623,052,031
With that explanation out of the way, let's continue. Next, we take the number 623,052,031 and divide it by 2:
623,052,031 ÷ 2 = 311,526,015.5
If the quotient is a whole number, then 2 and 311,526,015.5 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 | 623,052,031 | |
| -1 | -623,052,031 |
Now, we try dividing 623,052,031 by 3:
623,052,031 ÷ 3 = 207,684,010.3333
If the quotient is a whole number, then 3 and 207,684,010.3333 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 | 623,052,031 | |
| -1 | -623,052,031 |
Let's try dividing by 4:
623,052,031 ÷ 4 = 155,763,007.75
If the quotient is a whole number, then 4 and 155,763,007.75 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 | 623,052,031 | |
| -1 | 623,052,031 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 287 | 911 | 2,383 | 6,377 | 16,681 | 37,351 | 97,703 | 261,457 | 683,921 | 2,170,913 | 15,196,391 | 89,007,433 | 623,052,031 |
| -1 | -7 | -41 | -287 | -911 | -2,383 | -6,377 | -16,681 | -37,351 | -97,703 | -261,457 | -683,921 | -2,170,913 | -15,196,391 | -89,007,433 | -623,052,031 |
