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 33,147,583, 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 | 33,147,583 | |
| -1 | -33,147,583 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,147,583.
Example:
1 x 33,147,583 = 33,147,583
and
-1 x -33,147,583 = 33,147,583
Notice both answers equal 33,147,583
With that explanation out of the way, let's continue. Next, we take the number 33,147,583 and divide it by 2:
33,147,583 ÷ 2 = 16,573,791.5
If the quotient is a whole number, then 2 and 16,573,791.5 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 | 33,147,583 | |
| -1 | -33,147,583 |
Now, we try dividing 33,147,583 by 3:
33,147,583 ÷ 3 = 11,049,194.3333
If the quotient is a whole number, then 3 and 11,049,194.3333 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 | 33,147,583 | |
| -1 | -33,147,583 |
Let's try dividing by 4:
33,147,583 ÷ 4 = 8,286,895.75
If the quotient is a whole number, then 4 and 8,286,895.75 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 | 33,147,583 | |
| -1 | 33,147,583 |
If you did it right, you will end up with this table:
| 1 | 7 | 61 | 149 | 427 | 521 | 1,043 | 3,647 | 9,089 | 31,781 | 63,623 | 77,629 | 222,467 | 543,403 | 4,735,369 | 33,147,583 |
| -1 | -7 | -61 | -149 | -427 | -521 | -1,043 | -3,647 | -9,089 | -31,781 | -63,623 | -77,629 | -222,467 | -543,403 | -4,735,369 | -33,147,583 |
