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 5,786,515, 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 | 5,786,515 | |
| -1 | -5,786,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,786,515.
Example:
1 x 5,786,515 = 5,786,515
and
-1 x -5,786,515 = 5,786,515
Notice both answers equal 5,786,515
With that explanation out of the way, let's continue. Next, we take the number 5,786,515 and divide it by 2:
5,786,515 ÷ 2 = 2,893,257.5
If the quotient is a whole number, then 2 and 2,893,257.5 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 | 5,786,515 | |
| -1 | -5,786,515 |
Now, we try dividing 5,786,515 by 3:
5,786,515 ÷ 3 = 1,928,838.3333
If the quotient is a whole number, then 3 and 1,928,838.3333 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 | 5,786,515 | |
| -1 | -5,786,515 |
Let's try dividing by 4:
5,786,515 ÷ 4 = 1,446,628.75
If the quotient is a whole number, then 4 and 1,446,628.75 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 | 5,786,515 | |
| -1 | 5,786,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 145 | 203 | 1,015 | 5,701 | 28,505 | 39,907 | 165,329 | 199,535 | 826,645 | 1,157,303 | 5,786,515 |
| -1 | -5 | -7 | -29 | -35 | -145 | -203 | -1,015 | -5,701 | -28,505 | -39,907 | -165,329 | -199,535 | -826,645 | -1,157,303 | -5,786,515 |
