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 3,580,655, 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 | 3,580,655 | |
| -1 | -3,580,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,580,655.
Example:
1 x 3,580,655 = 3,580,655
and
-1 x -3,580,655 = 3,580,655
Notice both answers equal 3,580,655
With that explanation out of the way, let's continue. Next, we take the number 3,580,655 and divide it by 2:
3,580,655 ÷ 2 = 1,790,327.5
If the quotient is a whole number, then 2 and 1,790,327.5 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 | 3,580,655 | |
| -1 | -3,580,655 |
Now, we try dividing 3,580,655 by 3:
3,580,655 ÷ 3 = 1,193,551.6667
If the quotient is a whole number, then 3 and 1,193,551.6667 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 | 3,580,655 | |
| -1 | -3,580,655 |
Let's try dividing by 4:
3,580,655 ÷ 4 = 895,163.75
If the quotient is a whole number, then 4 and 895,163.75 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 | 3,580,655 | |
| -1 | 3,580,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 31 | 65 | 155 | 403 | 1,777 | 2,015 | 8,885 | 23,101 | 55,087 | 115,505 | 275,435 | 716,131 | 3,580,655 |
| -1 | -5 | -13 | -31 | -65 | -155 | -403 | -1,777 | -2,015 | -8,885 | -23,101 | -55,087 | -115,505 | -275,435 | -716,131 | -3,580,655 |
