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 20,032,537, 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 | 20,032,537 | |
| -1 | -20,032,537 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,032,537.
Example:
1 x 20,032,537 = 20,032,537
and
-1 x -20,032,537 = 20,032,537
Notice both answers equal 20,032,537
With that explanation out of the way, let's continue. Next, we take the number 20,032,537 and divide it by 2:
20,032,537 ÷ 2 = 10,016,268.5
If the quotient is a whole number, then 2 and 10,016,268.5 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 | 20,032,537 | |
| -1 | -20,032,537 |
Now, we try dividing 20,032,537 by 3:
20,032,537 ÷ 3 = 6,677,512.3333
If the quotient is a whole number, then 3 and 6,677,512.3333 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 | 20,032,537 | |
| -1 | -20,032,537 |
Let's try dividing by 4:
20,032,537 ÷ 4 = 5,008,134.25
If the quotient is a whole number, then 4 and 5,008,134.25 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 | 20,032,537 | |
| -1 | 20,032,537 |
If you did it right, you will end up with this table:
| 1 | 7 | 97 | 163 | 181 | 679 | 1,141 | 1,267 | 15,811 | 17,557 | 29,503 | 110,677 | 122,899 | 206,521 | 2,861,791 | 20,032,537 |
| -1 | -7 | -97 | -163 | -181 | -679 | -1,141 | -1,267 | -15,811 | -17,557 | -29,503 | -110,677 | -122,899 | -206,521 | -2,861,791 | -20,032,537 |
