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 36,156,715, 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 | 36,156,715 | |
| -1 | -36,156,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 36,156,715.
Example:
1 x 36,156,715 = 36,156,715
and
-1 x -36,156,715 = 36,156,715
Notice both answers equal 36,156,715
With that explanation out of the way, let's continue. Next, we take the number 36,156,715 and divide it by 2:
36,156,715 ÷ 2 = 18,078,357.5
If the quotient is a whole number, then 2 and 18,078,357.5 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 | 36,156,715 | |
| -1 | -36,156,715 |
Now, we try dividing 36,156,715 by 3:
36,156,715 ÷ 3 = 12,052,238.3333
If the quotient is a whole number, then 3 and 12,052,238.3333 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 | 36,156,715 | |
| -1 | -36,156,715 |
Let's try dividing by 4:
36,156,715 ÷ 4 = 9,039,178.75
If the quotient is a whole number, then 4 and 9,039,178.75 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 | 36,156,715 | |
| -1 | 36,156,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 54,371 | 271,855 | 380,597 | 1,033,049 | 1,902,985 | 5,165,245 | 7,231,343 | 36,156,715 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -54,371 | -271,855 | -380,597 | -1,033,049 | -1,902,985 | -5,165,245 | -7,231,343 | -36,156,715 |
