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 33,423,355, 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 | 33,423,355 | |
| -1 | -33,423,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,423,355.
Example:
1 x 33,423,355 = 33,423,355
and
-1 x -33,423,355 = 33,423,355
Notice both answers equal 33,423,355
With that explanation out of the way, let's continue. Next, we take the number 33,423,355 and divide it by 2:
33,423,355 ÷ 2 = 16,711,677.5
If the quotient is a whole number, then 2 and 16,711,677.5 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 | 33,423,355 | |
| -1 | -33,423,355 |
Now, we try dividing 33,423,355 by 3:
33,423,355 ÷ 3 = 11,141,118.3333
If the quotient is a whole number, then 3 and 11,141,118.3333 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 | 33,423,355 | |
| -1 | -33,423,355 |
Let's try dividing by 4:
33,423,355 ÷ 4 = 8,355,838.75
If the quotient is a whole number, then 4 and 8,355,838.75 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 | 33,423,355 | |
| -1 | 33,423,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 263 | 1,315 | 1,841 | 3,631 | 9,205 | 18,155 | 25,417 | 127,085 | 954,953 | 4,774,765 | 6,684,671 | 33,423,355 |
| -1 | -5 | -7 | -35 | -263 | -1,315 | -1,841 | -3,631 | -9,205 | -18,155 | -25,417 | -127,085 | -954,953 | -4,774,765 | -6,684,671 | -33,423,355 |
