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 33,118,745, 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 | 33,118,745 | |
| -1 | -33,118,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,118,745.
Example:
1 x 33,118,745 = 33,118,745
and
-1 x -33,118,745 = 33,118,745
Notice both answers equal 33,118,745
With that explanation out of the way, let's continue. Next, we take the number 33,118,745 and divide it by 2:
33,118,745 ÷ 2 = 16,559,372.5
If the quotient is a whole number, then 2 and 16,559,372.5 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 | 33,118,745 | |
| -1 | -33,118,745 |
Now, we try dividing 33,118,745 by 3:
33,118,745 ÷ 3 = 11,039,581.6667
If the quotient is a whole number, then 3 and 11,039,581.6667 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 | 33,118,745 | |
| -1 | -33,118,745 |
Let's try dividing by 4:
33,118,745 ÷ 4 = 8,279,686.25
If the quotient is a whole number, then 4 and 8,279,686.25 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 | 33,118,745 | |
| -1 | 33,118,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 701 | 859 | 3,505 | 4,295 | 7,711 | 9,449 | 38,555 | 47,245 | 602,159 | 3,010,795 | 6,623,749 | 33,118,745 |
| -1 | -5 | -11 | -55 | -701 | -859 | -3,505 | -4,295 | -7,711 | -9,449 | -38,555 | -47,245 | -602,159 | -3,010,795 | -6,623,749 | -33,118,745 |
