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 33,422,137, 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 | 33,422,137 | |
| -1 | -33,422,137 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,422,137.
Example:
1 x 33,422,137 = 33,422,137
and
-1 x -33,422,137 = 33,422,137
Notice both answers equal 33,422,137
With that explanation out of the way, let's continue. Next, we take the number 33,422,137 and divide it by 2:
33,422,137 ÷ 2 = 16,711,068.5
If the quotient is a whole number, then 2 and 16,711,068.5 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 | 33,422,137 | |
| -1 | -33,422,137 |
Now, we try dividing 33,422,137 by 3:
33,422,137 ÷ 3 = 11,140,712.3333
If the quotient is a whole number, then 3 and 11,140,712.3333 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 | 33,422,137 | |
| -1 | -33,422,137 |
Let's try dividing by 4:
33,422,137 ÷ 4 = 8,355,534.25
If the quotient is a whole number, then 4 and 8,355,534.25 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 | 33,422,137 | |
| -1 | 33,422,137 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 43 | 259 | 301 | 1,591 | 3,001 | 11,137 | 21,007 | 111,037 | 129,043 | 777,259 | 903,301 | 4,774,591 | 33,422,137 |
| -1 | -7 | -37 | -43 | -259 | -301 | -1,591 | -3,001 | -11,137 | -21,007 | -111,037 | -129,043 | -777,259 | -903,301 | -4,774,591 | -33,422,137 |
