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 5,321,057, 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 | 5,321,057 | |
| -1 | -5,321,057 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,321,057.
Example:
1 x 5,321,057 = 5,321,057
and
-1 x -5,321,057 = 5,321,057
Notice both answers equal 5,321,057
With that explanation out of the way, let's continue. Next, we take the number 5,321,057 and divide it by 2:
5,321,057 ÷ 2 = 2,660,528.5
If the quotient is a whole number, then 2 and 2,660,528.5 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 | 5,321,057 | |
| -1 | -5,321,057 |
Now, we try dividing 5,321,057 by 3:
5,321,057 ÷ 3 = 1,773,685.6667
If the quotient is a whole number, then 3 and 1,773,685.6667 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 | 5,321,057 | |
| -1 | -5,321,057 |
Let's try dividing by 4:
5,321,057 ÷ 4 = 1,330,264.25
If the quotient is a whole number, then 4 and 1,330,264.25 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 | 5,321,057 | |
| -1 | 5,321,057 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 49 | 113 | 217 | 791 | 961 | 1,519 | 3,503 | 5,537 | 6,727 | 24,521 | 47,089 | 108,593 | 171,647 | 760,151 | 5,321,057 |
| -1 | -7 | -31 | -49 | -113 | -217 | -791 | -961 | -1,519 | -3,503 | -5,537 | -6,727 | -24,521 | -47,089 | -108,593 | -171,647 | -760,151 | -5,321,057 |
