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 36,503,665, 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 | 36,503,665 | |
| -1 | -36,503,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 36,503,665.
Example:
1 x 36,503,665 = 36,503,665
and
-1 x -36,503,665 = 36,503,665
Notice both answers equal 36,503,665
With that explanation out of the way, let's continue. Next, we take the number 36,503,665 and divide it by 2:
36,503,665 ÷ 2 = 18,251,832.5
If the quotient is a whole number, then 2 and 18,251,832.5 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 | 36,503,665 | |
| -1 | -36,503,665 |
Now, we try dividing 36,503,665 by 3:
36,503,665 ÷ 3 = 12,167,888.3333
If the quotient is a whole number, then 3 and 12,167,888.3333 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 | 36,503,665 | |
| -1 | -36,503,665 |
Let's try dividing by 4:
36,503,665 ÷ 4 = 9,125,916.25
If the quotient is a whole number, then 4 and 9,125,916.25 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 | 36,503,665 | |
| -1 | 36,503,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 239 | 1,195 | 2,629 | 2,777 | 13,145 | 13,885 | 30,547 | 152,735 | 663,703 | 3,318,515 | 7,300,733 | 36,503,665 |
| -1 | -5 | -11 | -55 | -239 | -1,195 | -2,629 | -2,777 | -13,145 | -13,885 | -30,547 | -152,735 | -663,703 | -3,318,515 | -7,300,733 | -36,503,665 |
