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 22,445,616, 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 | 22,445,616 | |
| -1 | -22,445,616 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,445,616.
Example:
1 x 22,445,616 = 22,445,616
and
-1 x -22,445,616 = 22,445,616
Notice both answers equal 22,445,616
With that explanation out of the way, let's continue. Next, we take the number 22,445,616 and divide it by 2:
22,445,616 ÷ 2 = 11,222,808
If the quotient is a whole number, then 2 and 11,222,808 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 11,222,808 | 22,445,616 | |
| -1 | -2 | -11,222,808 | -22,445,616 |
Now, we try dividing 22,445,616 by 3:
22,445,616 ÷ 3 = 7,481,872
If the quotient is a whole number, then 3 and 7,481,872 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 3 | 7,481,872 | 11,222,808 | 22,445,616 | |
| -1 | -2 | -3 | -7,481,872 | -11,222,808 | -22,445,616 |
Let's try dividing by 4:
22,445,616 ÷ 4 = 5,611,404
If the quotient is a whole number, then 4 and 5,611,404 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 3 | 4 | 5,611,404 | 7,481,872 | 11,222,808 | 22,445,616 | |
| -1 | -2 | -3 | -4 | -5,611,404 | -7,481,872 | -11,222,808 | 22,445,616 |
If you did it right, you will end up with this table:
| 1 | 2 | 3 | 4 | 6 | 8 | 12 | 16 | 24 | 48 | 467,617 | 935,234 | 1,402,851 | 1,870,468 | 2,805,702 | 3,740,936 | 5,611,404 | 7,481,872 | 11,222,808 | 22,445,616 |
| -1 | -2 | -3 | -4 | -6 | -8 | -12 | -16 | -24 | -48 | -467,617 | -935,234 | -1,402,851 | -1,870,468 | -2,805,702 | -3,740,936 | -5,611,404 | -7,481,872 | -11,222,808 | -22,445,616 |
