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 22,145,435, 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 | 22,145,435 | |
| -1 | -22,145,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,145,435.
Example:
1 x 22,145,435 = 22,145,435
and
-1 x -22,145,435 = 22,145,435
Notice both answers equal 22,145,435
With that explanation out of the way, let's continue. Next, we take the number 22,145,435 and divide it by 2:
22,145,435 ÷ 2 = 11,072,717.5
If the quotient is a whole number, then 2 and 11,072,717.5 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 | 22,145,435 | |
| -1 | -22,145,435 |
Now, we try dividing 22,145,435 by 3:
22,145,435 ÷ 3 = 7,381,811.6667
If the quotient is a whole number, then 3 and 7,381,811.6667 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 | 22,145,435 | |
| -1 | -22,145,435 |
Let's try dividing by 4:
22,145,435 ÷ 4 = 5,536,358.75
If the quotient is a whole number, then 4 and 5,536,358.75 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 | 22,145,435 | |
| -1 | 22,145,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 23 | 65 | 115 | 299 | 1,495 | 14,813 | 74,065 | 192,569 | 340,699 | 962,845 | 1,703,495 | 4,429,087 | 22,145,435 |
| -1 | -5 | -13 | -23 | -65 | -115 | -299 | -1,495 | -14,813 | -74,065 | -192,569 | -340,699 | -962,845 | -1,703,495 | -4,429,087 | -22,145,435 |
