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 22,015,435, 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 | 22,015,435 | |
| -1 | -22,015,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,015,435.
Example:
1 x 22,015,435 = 22,015,435
and
-1 x -22,015,435 = 22,015,435
Notice both answers equal 22,015,435
With that explanation out of the way, let's continue. Next, we take the number 22,015,435 and divide it by 2:
22,015,435 ÷ 2 = 11,007,717.5
If the quotient is a whole number, then 2 and 11,007,717.5 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 | 22,015,435 | |
| -1 | -22,015,435 |
Now, we try dividing 22,015,435 by 3:
22,015,435 ÷ 3 = 7,338,478.3333
If the quotient is a whole number, then 3 and 7,338,478.3333 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 | 22,015,435 | |
| -1 | -22,015,435 |
Let's try dividing by 4:
22,015,435 ÷ 4 = 5,503,858.75
If the quotient is a whole number, then 4 and 5,503,858.75 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 | 22,015,435 | |
| -1 | 22,015,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 577 | 587 | 2,885 | 2,935 | 7,501 | 7,631 | 37,505 | 38,155 | 338,699 | 1,693,495 | 4,403,087 | 22,015,435 |
| -1 | -5 | -13 | -65 | -577 | -587 | -2,885 | -2,935 | -7,501 | -7,631 | -37,505 | -38,155 | -338,699 | -1,693,495 | -4,403,087 | -22,015,435 |
