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 5,316,563, 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 | 5,316,563 | |
| -1 | -5,316,563 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,316,563.
Example:
1 x 5,316,563 = 5,316,563
and
-1 x -5,316,563 = 5,316,563
Notice both answers equal 5,316,563
With that explanation out of the way, let's continue. Next, we take the number 5,316,563 and divide it by 2:
5,316,563 ÷ 2 = 2,658,281.5
If the quotient is a whole number, then 2 and 2,658,281.5 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 | 5,316,563 | |
| -1 | -5,316,563 |
Now, we try dividing 5,316,563 by 3:
5,316,563 ÷ 3 = 1,772,187.6667
If the quotient is a whole number, then 3 and 1,772,187.6667 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 | 5,316,563 | |
| -1 | -5,316,563 |
Let's try dividing by 4:
5,316,563 ÷ 4 = 1,329,140.75
If the quotient is a whole number, then 4 and 1,329,140.75 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 | 5,316,563 | |
| -1 | 5,316,563 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 43 | 119 | 301 | 731 | 1,039 | 5,117 | 7,273 | 17,663 | 44,677 | 123,641 | 312,739 | 759,509 | 5,316,563 |
| -1 | -7 | -17 | -43 | -119 | -301 | -731 | -1,039 | -5,117 | -7,273 | -17,663 | -44,677 | -123,641 | -312,739 | -759,509 | -5,316,563 |
