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 5,712,785, 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 | 5,712,785 | |
| -1 | -5,712,785 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,712,785.
Example:
1 x 5,712,785 = 5,712,785
and
-1 x -5,712,785 = 5,712,785
Notice both answers equal 5,712,785
With that explanation out of the way, let's continue. Next, we take the number 5,712,785 and divide it by 2:
5,712,785 ÷ 2 = 2,856,392.5
If the quotient is a whole number, then 2 and 2,856,392.5 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 | 5,712,785 | |
| -1 | -5,712,785 |
Now, we try dividing 5,712,785 by 3:
5,712,785 ÷ 3 = 1,904,261.6667
If the quotient is a whole number, then 3 and 1,904,261.6667 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 | 5,712,785 | |
| -1 | -5,712,785 |
Let's try dividing by 4:
5,712,785 ÷ 4 = 1,428,196.25
If the quotient is a whole number, then 4 and 1,428,196.25 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 | 5,712,785 | |
| -1 | 5,712,785 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 179 | 491 | 895 | 2,327 | 2,455 | 6,383 | 11,635 | 31,915 | 87,889 | 439,445 | 1,142,557 | 5,712,785 |
| -1 | -5 | -13 | -65 | -179 | -491 | -895 | -2,327 | -2,455 | -6,383 | -11,635 | -31,915 | -87,889 | -439,445 | -1,142,557 | -5,712,785 |
