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 22,251,235, 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 | 22,251,235 | |
| -1 | -22,251,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,251,235.
Example:
1 x 22,251,235 = 22,251,235
and
-1 x -22,251,235 = 22,251,235
Notice both answers equal 22,251,235
With that explanation out of the way, let's continue. Next, we take the number 22,251,235 and divide it by 2:
22,251,235 ÷ 2 = 11,125,617.5
If the quotient is a whole number, then 2 and 11,125,617.5 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 | 22,251,235 | |
| -1 | -22,251,235 |
Now, we try dividing 22,251,235 by 3:
22,251,235 ÷ 3 = 7,417,078.3333
If the quotient is a whole number, then 3 and 7,417,078.3333 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 | 22,251,235 | |
| -1 | -22,251,235 |
Let's try dividing by 4:
22,251,235 ÷ 4 = 5,562,808.75
If the quotient is a whole number, then 4 and 5,562,808.75 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 | 22,251,235 | |
| -1 | 22,251,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 181 | 905 | 1,069 | 4,163 | 5,345 | 20,815 | 24,587 | 122,935 | 193,489 | 967,445 | 4,450,247 | 22,251,235 |
| -1 | -5 | -23 | -115 | -181 | -905 | -1,069 | -4,163 | -5,345 | -20,815 | -24,587 | -122,935 | -193,489 | -967,445 | -4,450,247 | -22,251,235 |
