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 33,237,673, 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 | 33,237,673 | |
| -1 | -33,237,673 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,237,673.
Example:
1 x 33,237,673 = 33,237,673
and
-1 x -33,237,673 = 33,237,673
Notice both answers equal 33,237,673
With that explanation out of the way, let's continue. Next, we take the number 33,237,673 and divide it by 2:
33,237,673 ÷ 2 = 16,618,836.5
If the quotient is a whole number, then 2 and 16,618,836.5 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 | 33,237,673 | |
| -1 | -33,237,673 |
Now, we try dividing 33,237,673 by 3:
33,237,673 ÷ 3 = 11,079,224.3333
If the quotient is a whole number, then 3 and 11,079,224.3333 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 | 33,237,673 | |
| -1 | -33,237,673 |
Let's try dividing by 4:
33,237,673 ÷ 4 = 8,309,418.25
If the quotient is a whole number, then 4 and 8,309,418.25 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 | 33,237,673 | |
| -1 | 33,237,673 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 89 | 217 | 623 | 1,721 | 2,759 | 12,047 | 19,313 | 53,351 | 153,169 | 373,457 | 1,072,183 | 4,748,239 | 33,237,673 |
| -1 | -7 | -31 | -89 | -217 | -623 | -1,721 | -2,759 | -12,047 | -19,313 | -53,351 | -153,169 | -373,457 | -1,072,183 | -4,748,239 | -33,237,673 |
