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 637,362,589, 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 | 637,362,589 | |
| -1 | -637,362,589 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 637,362,589.
Example:
1 x 637,362,589 = 637,362,589
and
-1 x -637,362,589 = 637,362,589
Notice both answers equal 637,362,589
With that explanation out of the way, let's continue. Next, we take the number 637,362,589 and divide it by 2:
637,362,589 ÷ 2 = 318,681,294.5
If the quotient is a whole number, then 2 and 318,681,294.5 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 | 637,362,589 | |
| -1 | -637,362,589 |
Now, we try dividing 637,362,589 by 3:
637,362,589 ÷ 3 = 212,454,196.3333
If the quotient is a whole number, then 3 and 212,454,196.3333 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 | 637,362,589 | |
| -1 | -637,362,589 |
Let's try dividing by 4:
637,362,589 ÷ 4 = 159,340,647.25
If the quotient is a whole number, then 4 and 159,340,647.25 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 | 637,362,589 | |
| -1 | 637,362,589 |
If you did it right, you will end up with this table:
| 1 | 17 | 41 | 439 | 697 | 2,083 | 7,463 | 17,999 | 35,411 | 85,403 | 305,983 | 914,437 | 1,451,851 | 15,545,429 | 37,491,917 | 637,362,589 |
| -1 | -17 | -41 | -439 | -697 | -2,083 | -7,463 | -17,999 | -35,411 | -85,403 | -305,983 | -914,437 | -1,451,851 | -15,545,429 | -37,491,917 | -637,362,589 |
