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 33,177,865, 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 | 33,177,865 | |
| -1 | -33,177,865 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,177,865.
Example:
1 x 33,177,865 = 33,177,865
and
-1 x -33,177,865 = 33,177,865
Notice both answers equal 33,177,865
With that explanation out of the way, let's continue. Next, we take the number 33,177,865 and divide it by 2:
33,177,865 ÷ 2 = 16,588,932.5
If the quotient is a whole number, then 2 and 16,588,932.5 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 | 33,177,865 | |
| -1 | -33,177,865 |
Now, we try dividing 33,177,865 by 3:
33,177,865 ÷ 3 = 11,059,288.3333
If the quotient is a whole number, then 3 and 11,059,288.3333 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 | 33,177,865 | |
| -1 | -33,177,865 |
Let's try dividing by 4:
33,177,865 ÷ 4 = 8,294,466.25
If the quotient is a whole number, then 4 and 8,294,466.25 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 | 33,177,865 | |
| -1 | 33,177,865 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 89 | 445 | 623 | 3,115 | 10,651 | 53,255 | 74,557 | 372,785 | 947,939 | 4,739,695 | 6,635,573 | 33,177,865 |
| -1 | -5 | -7 | -35 | -89 | -445 | -623 | -3,115 | -10,651 | -53,255 | -74,557 | -372,785 | -947,939 | -4,739,695 | -6,635,573 | -33,177,865 |
