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 3,491,561, 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 | 3,491,561 | |
| -1 | -3,491,561 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,491,561.
Example:
1 x 3,491,561 = 3,491,561
and
-1 x -3,491,561 = 3,491,561
Notice both answers equal 3,491,561
With that explanation out of the way, let's continue. Next, we take the number 3,491,561 and divide it by 2:
3,491,561 ÷ 2 = 1,745,780.5
If the quotient is a whole number, then 2 and 1,745,780.5 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 | 3,491,561 | |
| -1 | -3,491,561 |
Now, we try dividing 3,491,561 by 3:
3,491,561 ÷ 3 = 1,163,853.6667
If the quotient is a whole number, then 3 and 1,163,853.6667 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 | 3,491,561 | |
| -1 | -3,491,561 |
Let's try dividing by 4:
3,491,561 ÷ 4 = 872,890.25
If the quotient is a whole number, then 4 and 872,890.25 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 | 3,491,561 | |
| -1 | 3,491,561 |
If you did it right, you will end up with this table:
| 1 | 23 | 31 | 59 | 83 | 713 | 1,357 | 1,829 | 1,909 | 2,573 | 4,897 | 42,067 | 59,179 | 112,631 | 151,807 | 3,491,561 |
| -1 | -23 | -31 | -59 | -83 | -713 | -1,357 | -1,829 | -1,909 | -2,573 | -4,897 | -42,067 | -59,179 | -112,631 | -151,807 | -3,491,561 |
