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 5,090,965, 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 | 5,090,965 | |
| -1 | -5,090,965 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,090,965.
Example:
1 x 5,090,965 = 5,090,965
and
-1 x -5,090,965 = 5,090,965
Notice both answers equal 5,090,965
With that explanation out of the way, let's continue. Next, we take the number 5,090,965 and divide it by 2:
5,090,965 ÷ 2 = 2,545,482.5
If the quotient is a whole number, then 2 and 2,545,482.5 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 | 5,090,965 | |
| -1 | -5,090,965 |
Now, we try dividing 5,090,965 by 3:
5,090,965 ÷ 3 = 1,696,988.3333
If the quotient is a whole number, then 3 and 1,696,988.3333 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 | 5,090,965 | |
| -1 | -5,090,965 |
Let's try dividing by 4:
5,090,965 ÷ 4 = 1,272,741.25
If the quotient is a whole number, then 4 and 1,272,741.25 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 | 5,090,965 | |
| -1 | 5,090,965 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 151 | 613 | 755 | 1,661 | 3,065 | 6,743 | 8,305 | 33,715 | 92,563 | 462,815 | 1,018,193 | 5,090,965 |
| -1 | -5 | -11 | -55 | -151 | -613 | -755 | -1,661 | -3,065 | -6,743 | -8,305 | -33,715 | -92,563 | -462,815 | -1,018,193 | -5,090,965 |
