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 22,410,505, 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 | 22,410,505 | |
| -1 | -22,410,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,410,505.
Example:
1 x 22,410,505 = 22,410,505
and
-1 x -22,410,505 = 22,410,505
Notice both answers equal 22,410,505
With that explanation out of the way, let's continue. Next, we take the number 22,410,505 and divide it by 2:
22,410,505 ÷ 2 = 11,205,252.5
If the quotient is a whole number, then 2 and 11,205,252.5 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 | 22,410,505 | |
| -1 | -22,410,505 |
Now, we try dividing 22,410,505 by 3:
22,410,505 ÷ 3 = 7,470,168.3333
If the quotient is a whole number, then 3 and 7,470,168.3333 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 | 22,410,505 | |
| -1 | -22,410,505 |
Let's try dividing by 4:
22,410,505 ÷ 4 = 5,602,626.25
If the quotient is a whole number, then 4 and 5,602,626.25 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 | 22,410,505 | |
| -1 | 22,410,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 221 | 289 | 1,105 | 1,193 | 1,445 | 3,757 | 5,965 | 15,509 | 18,785 | 20,281 | 77,545 | 101,405 | 263,653 | 344,777 | 1,318,265 | 1,723,885 | 4,482,101 | 22,410,505 |
| -1 | -5 | -13 | -17 | -65 | -85 | -221 | -289 | -1,105 | -1,193 | -1,445 | -3,757 | -5,965 | -15,509 | -18,785 | -20,281 | -77,545 | -101,405 | -263,653 | -344,777 | -1,318,265 | -1,723,885 | -4,482,101 | -22,410,505 |
