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 3,597,581, 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 | 3,597,581 | |
| -1 | -3,597,581 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,597,581.
Example:
1 x 3,597,581 = 3,597,581
and
-1 x -3,597,581 = 3,597,581
Notice both answers equal 3,597,581
With that explanation out of the way, let's continue. Next, we take the number 3,597,581 and divide it by 2:
3,597,581 ÷ 2 = 1,798,790.5
If the quotient is a whole number, then 2 and 1,798,790.5 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 | 3,597,581 | |
| -1 | -3,597,581 |
Now, we try dividing 3,597,581 by 3:
3,597,581 ÷ 3 = 1,199,193.6667
If the quotient is a whole number, then 3 and 1,199,193.6667 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 | 3,597,581 | |
| -1 | -3,597,581 |
Let's try dividing by 4:
3,597,581 ÷ 4 = 899,395.25
If the quotient is a whole number, then 4 and 899,395.25 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 | 3,597,581 | |
| -1 | 3,597,581 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 79 | 113 | 403 | 1,027 | 1,469 | 2,449 | 3,503 | 8,927 | 31,837 | 45,539 | 116,051 | 276,737 | 3,597,581 |
| -1 | -13 | -31 | -79 | -113 | -403 | -1,027 | -1,469 | -2,449 | -3,503 | -8,927 | -31,837 | -45,539 | -116,051 | -276,737 | -3,597,581 |
