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 22,070,945, 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 | 22,070,945 | |
| -1 | -22,070,945 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,070,945.
Example:
1 x 22,070,945 = 22,070,945
and
-1 x -22,070,945 = 22,070,945
Notice both answers equal 22,070,945
With that explanation out of the way, let's continue. Next, we take the number 22,070,945 and divide it by 2:
22,070,945 ÷ 2 = 11,035,472.5
If the quotient is a whole number, then 2 and 11,035,472.5 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 | 22,070,945 | |
| -1 | -22,070,945 |
Now, we try dividing 22,070,945 by 3:
22,070,945 ÷ 3 = 7,356,981.6667
If the quotient is a whole number, then 3 and 7,356,981.6667 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 | 22,070,945 | |
| -1 | -22,070,945 |
Let's try dividing by 4:
22,070,945 ÷ 4 = 5,517,736.25
If the quotient is a whole number, then 4 and 5,517,736.25 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 | 22,070,945 | |
| -1 | 22,070,945 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 83 | 415 | 1,079 | 4,091 | 5,395 | 20,455 | 53,183 | 265,915 | 339,553 | 1,697,765 | 4,414,189 | 22,070,945 |
| -1 | -5 | -13 | -65 | -83 | -415 | -1,079 | -4,091 | -5,395 | -20,455 | -53,183 | -265,915 | -339,553 | -1,697,765 | -4,414,189 | -22,070,945 |
