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 5,040,565, 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 | 5,040,565 | |
| -1 | -5,040,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,040,565.
Example:
1 x 5,040,565 = 5,040,565
and
-1 x -5,040,565 = 5,040,565
Notice both answers equal 5,040,565
With that explanation out of the way, let's continue. Next, we take the number 5,040,565 and divide it by 2:
5,040,565 ÷ 2 = 2,520,282.5
If the quotient is a whole number, then 2 and 2,520,282.5 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 | 5,040,565 | |
| -1 | -5,040,565 |
Now, we try dividing 5,040,565 by 3:
5,040,565 ÷ 3 = 1,680,188.3333
If the quotient is a whole number, then 3 and 1,680,188.3333 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 | 5,040,565 | |
| -1 | -5,040,565 |
Let's try dividing by 4:
5,040,565 ÷ 4 = 1,260,141.25
If the quotient is a whole number, then 4 and 1,260,141.25 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 | 5,040,565 | |
| -1 | 5,040,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 53 | 115 | 265 | 827 | 1,219 | 4,135 | 6,095 | 19,021 | 43,831 | 95,105 | 219,155 | 1,008,113 | 5,040,565 |
| -1 | -5 | -23 | -53 | -115 | -265 | -827 | -1,219 | -4,135 | -6,095 | -19,021 | -43,831 | -95,105 | -219,155 | -1,008,113 | -5,040,565 |
