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 5,686,919, 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 | 5,686,919 | |
| -1 | -5,686,919 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,686,919.
Example:
1 x 5,686,919 = 5,686,919
and
-1 x -5,686,919 = 5,686,919
Notice both answers equal 5,686,919
With that explanation out of the way, let's continue. Next, we take the number 5,686,919 and divide it by 2:
5,686,919 ÷ 2 = 2,843,459.5
If the quotient is a whole number, then 2 and 2,843,459.5 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 | 5,686,919 | |
| -1 | -5,686,919 |
Now, we try dividing 5,686,919 by 3:
5,686,919 ÷ 3 = 1,895,639.6667
If the quotient is a whole number, then 3 and 1,895,639.6667 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 | 5,686,919 | |
| -1 | -5,686,919 |
Let's try dividing by 4:
5,686,919 ÷ 4 = 1,421,729.75
If the quotient is a whole number, then 4 and 1,421,729.75 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 | 5,686,919 | |
| -1 | 5,686,919 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 73 | 217 | 359 | 511 | 2,263 | 2,513 | 11,129 | 15,841 | 26,207 | 77,903 | 183,449 | 812,417 | 5,686,919 |
| -1 | -7 | -31 | -73 | -217 | -359 | -511 | -2,263 | -2,513 | -11,129 | -15,841 | -26,207 | -77,903 | -183,449 | -812,417 | -5,686,919 |
