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 22,790,965, 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 | 22,790,965 | |
| -1 | -22,790,965 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,790,965.
Example:
1 x 22,790,965 = 22,790,965
and
-1 x -22,790,965 = 22,790,965
Notice both answers equal 22,790,965
With that explanation out of the way, let's continue. Next, we take the number 22,790,965 and divide it by 2:
22,790,965 ÷ 2 = 11,395,482.5
If the quotient is a whole number, then 2 and 11,395,482.5 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 | 22,790,965 | |
| -1 | -22,790,965 |
Now, we try dividing 22,790,965 by 3:
22,790,965 ÷ 3 = 7,596,988.3333
If the quotient is a whole number, then 3 and 7,596,988.3333 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 | 22,790,965 | |
| -1 | -22,790,965 |
Let's try dividing by 4:
22,790,965 ÷ 4 = 5,697,741.25
If the quotient is a whole number, then 4 and 5,697,741.25 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 | 22,790,965 | |
| -1 | 22,790,965 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 73 | 85 | 365 | 1,241 | 3,673 | 6,205 | 18,365 | 62,441 | 268,129 | 312,205 | 1,340,645 | 4,558,193 | 22,790,965 |
| -1 | -5 | -17 | -73 | -85 | -365 | -1,241 | -3,673 | -6,205 | -18,365 | -62,441 | -268,129 | -312,205 | -1,340,645 | -4,558,193 | -22,790,965 |
