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 36,020,117, 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 | 36,020,117 | |
| -1 | -36,020,117 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 36,020,117.
Example:
1 x 36,020,117 = 36,020,117
and
-1 x -36,020,117 = 36,020,117
Notice both answers equal 36,020,117
With that explanation out of the way, let's continue. Next, we take the number 36,020,117 and divide it by 2:
36,020,117 ÷ 2 = 18,010,058.5
If the quotient is a whole number, then 2 and 18,010,058.5 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 | 36,020,117 | |
| -1 | -36,020,117 |
Now, we try dividing 36,020,117 by 3:
36,020,117 ÷ 3 = 12,006,705.6667
If the quotient is a whole number, then 3 and 12,006,705.6667 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 | 36,020,117 | |
| -1 | -36,020,117 |
Let's try dividing by 4:
36,020,117 ÷ 4 = 9,005,029.25
If the quotient is a whole number, then 4 and 9,005,029.25 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 | 36,020,117 | |
| -1 | 36,020,117 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 191 | 203 | 929 | 1,337 | 5,539 | 6,503 | 26,941 | 38,773 | 177,439 | 188,587 | 1,242,073 | 5,145,731 | 36,020,117 |
| -1 | -7 | -29 | -191 | -203 | -929 | -1,337 | -5,539 | -6,503 | -26,941 | -38,773 | -177,439 | -188,587 | -1,242,073 | -5,145,731 | -36,020,117 |
