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 103,896,589, 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 | 103,896,589 | |
| -1 | -103,896,589 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,896,589.
Example:
1 x 103,896,589 = 103,896,589
and
-1 x -103,896,589 = 103,896,589
Notice both answers equal 103,896,589
With that explanation out of the way, let's continue. Next, we take the number 103,896,589 and divide it by 2:
103,896,589 ÷ 2 = 51,948,294.5
If the quotient is a whole number, then 2 and 51,948,294.5 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 | 103,896,589 | |
| -1 | -103,896,589 |
Now, we try dividing 103,896,589 by 3:
103,896,589 ÷ 3 = 34,632,196.3333
If the quotient is a whole number, then 3 and 34,632,196.3333 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 | 103,896,589 | |
| -1 | -103,896,589 |
Let's try dividing by 4:
103,896,589 ÷ 4 = 25,974,147.25
If the quotient is a whole number, then 4 and 25,974,147.25 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 | 103,896,589 | |
| -1 | 103,896,589 |
If you did it right, you will end up with this table:
| 1 | 23 | 29 | 53 | 667 | 1,219 | 1,537 | 2,939 | 35,351 | 67,597 | 85,231 | 155,767 | 1,960,313 | 3,582,641 | 4,517,243 | 103,896,589 |
| -1 | -23 | -29 | -53 | -667 | -1,219 | -1,537 | -2,939 | -35,351 | -67,597 | -85,231 | -155,767 | -1,960,313 | -3,582,641 | -4,517,243 | -103,896,589 |
