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 36,442,021, 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 | 36,442,021 | |
| -1 | -36,442,021 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 36,442,021.
Example:
1 x 36,442,021 = 36,442,021
and
-1 x -36,442,021 = 36,442,021
Notice both answers equal 36,442,021
With that explanation out of the way, let's continue. Next, we take the number 36,442,021 and divide it by 2:
36,442,021 ÷ 2 = 18,221,010.5
If the quotient is a whole number, then 2 and 18,221,010.5 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 | 36,442,021 | |
| -1 | -36,442,021 |
Now, we try dividing 36,442,021 by 3:
36,442,021 ÷ 3 = 12,147,340.3333
If the quotient is a whole number, then 3 and 12,147,340.3333 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 | 36,442,021 | |
| -1 | -36,442,021 |
Let's try dividing by 4:
36,442,021 ÷ 4 = 9,110,505.25
If the quotient is a whole number, then 4 and 9,110,505.25 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 | 36,442,021 | |
| -1 | 36,442,021 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 211 | 1,477 | 2,243 | 2,321 | 15,701 | 16,247 | 24,673 | 172,711 | 473,273 | 3,312,911 | 5,206,003 | 36,442,021 |
| -1 | -7 | -11 | -77 | -211 | -1,477 | -2,243 | -2,321 | -15,701 | -16,247 | -24,673 | -172,711 | -473,273 | -3,312,911 | -5,206,003 | -36,442,021 |
