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 33,577,271, 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 | 33,577,271 | |
| -1 | -33,577,271 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,577,271.
Example:
1 x 33,577,271 = 33,577,271
and
-1 x -33,577,271 = 33,577,271
Notice both answers equal 33,577,271
With that explanation out of the way, let's continue. Next, we take the number 33,577,271 and divide it by 2:
33,577,271 ÷ 2 = 16,788,635.5
If the quotient is a whole number, then 2 and 16,788,635.5 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 | 33,577,271 | |
| -1 | -33,577,271 |
Now, we try dividing 33,577,271 by 3:
33,577,271 ÷ 3 = 11,192,423.6667
If the quotient is a whole number, then 3 and 11,192,423.6667 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 | 33,577,271 | |
| -1 | -33,577,271 |
Let's try dividing by 4:
33,577,271 ÷ 4 = 8,394,317.75
If the quotient is a whole number, then 4 and 8,394,317.75 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 | 33,577,271 | |
| -1 | 33,577,271 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 197 | 1,379 | 1,873 | 2,561 | 13,111 | 17,927 | 24,349 | 170,443 | 368,981 | 2,582,867 | 4,796,753 | 33,577,271 |
| -1 | -7 | -13 | -91 | -197 | -1,379 | -1,873 | -2,561 | -13,111 | -17,927 | -24,349 | -170,443 | -368,981 | -2,582,867 | -4,796,753 | -33,577,271 |
