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 7,040,561, 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 | 7,040,561 | |
| -1 | -7,040,561 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,040,561.
Example:
1 x 7,040,561 = 7,040,561
and
-1 x -7,040,561 = 7,040,561
Notice both answers equal 7,040,561
With that explanation out of the way, let's continue. Next, we take the number 7,040,561 and divide it by 2:
7,040,561 ÷ 2 = 3,520,280.5
If the quotient is a whole number, then 2 and 3,520,280.5 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 | 7,040,561 | |
| -1 | -7,040,561 |
Now, we try dividing 7,040,561 by 3:
7,040,561 ÷ 3 = 2,346,853.6667
If the quotient is a whole number, then 3 and 2,346,853.6667 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 | 7,040,561 | |
| -1 | -7,040,561 |
Let's try dividing by 4:
7,040,561 ÷ 4 = 1,760,140.25
If the quotient is a whole number, then 4 and 1,760,140.25 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 | 7,040,561 | |
| -1 | 7,040,561 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 67 | 233 | 451 | 737 | 2,563 | 2,747 | 9,553 | 15,611 | 30,217 | 105,083 | 171,721 | 640,051 | 7,040,561 |
| -1 | -11 | -41 | -67 | -233 | -451 | -737 | -2,563 | -2,747 | -9,553 | -15,611 | -30,217 | -105,083 | -171,721 | -640,051 | -7,040,561 |
