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 33,949,181, 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 | 33,949,181 | |
| -1 | -33,949,181 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,949,181.
Example:
1 x 33,949,181 = 33,949,181
and
-1 x -33,949,181 = 33,949,181
Notice both answers equal 33,949,181
With that explanation out of the way, let's continue. Next, we take the number 33,949,181 and divide it by 2:
33,949,181 ÷ 2 = 16,974,590.5
If the quotient is a whole number, then 2 and 16,974,590.5 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 | 33,949,181 | |
| -1 | -33,949,181 |
Now, we try dividing 33,949,181 by 3:
33,949,181 ÷ 3 = 11,316,393.6667
If the quotient is a whole number, then 3 and 11,316,393.6667 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 | 33,949,181 | |
| -1 | -33,949,181 |
Let's try dividing by 4:
33,949,181 ÷ 4 = 8,487,295.25
If the quotient is a whole number, then 4 and 8,487,295.25 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 | 33,949,181 | |
| -1 | 33,949,181 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 47 | 133 | 329 | 893 | 5,431 | 6,251 | 38,017 | 103,189 | 255,257 | 722,323 | 1,786,799 | 4,849,883 | 33,949,181 |
| -1 | -7 | -19 | -47 | -133 | -329 | -893 | -5,431 | -6,251 | -38,017 | -103,189 | -255,257 | -722,323 | -1,786,799 | -4,849,883 | -33,949,181 |
