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 33,442,423, 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 | 33,442,423 | |
| -1 | -33,442,423 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,442,423.
Example:
1 x 33,442,423 = 33,442,423
and
-1 x -33,442,423 = 33,442,423
Notice both answers equal 33,442,423
With that explanation out of the way, let's continue. Next, we take the number 33,442,423 and divide it by 2:
33,442,423 ÷ 2 = 16,721,211.5
If the quotient is a whole number, then 2 and 16,721,211.5 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 | 33,442,423 | |
| -1 | -33,442,423 |
Now, we try dividing 33,442,423 by 3:
33,442,423 ÷ 3 = 11,147,474.3333
If the quotient is a whole number, then 3 and 11,147,474.3333 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 | 33,442,423 | |
| -1 | -33,442,423 |
Let's try dividing by 4:
33,442,423 ÷ 4 = 8,360,605.75
If the quotient is a whole number, then 4 and 8,360,605.75 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 | 33,442,423 | |
| -1 | 33,442,423 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 151 | 203 | 1,057 | 1,091 | 4,379 | 7,637 | 30,653 | 31,639 | 164,741 | 221,473 | 1,153,187 | 4,777,489 | 33,442,423 |
| -1 | -7 | -29 | -151 | -203 | -1,057 | -1,091 | -4,379 | -7,637 | -30,653 | -31,639 | -164,741 | -221,473 | -1,153,187 | -4,777,489 | -33,442,423 |
