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 33,567,415, 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 | 33,567,415 | |
| -1 | -33,567,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,567,415.
Example:
1 x 33,567,415 = 33,567,415
and
-1 x -33,567,415 = 33,567,415
Notice both answers equal 33,567,415
With that explanation out of the way, let's continue. Next, we take the number 33,567,415 and divide it by 2:
33,567,415 ÷ 2 = 16,783,707.5
If the quotient is a whole number, then 2 and 16,783,707.5 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 | 33,567,415 | |
| -1 | -33,567,415 |
Now, we try dividing 33,567,415 by 3:
33,567,415 ÷ 3 = 11,189,138.3333
If the quotient is a whole number, then 3 and 11,189,138.3333 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 | 33,567,415 | |
| -1 | -33,567,415 |
Let's try dividing by 4:
33,567,415 ÷ 4 = 8,391,853.75
If the quotient is a whole number, then 4 and 8,391,853.75 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 | 33,567,415 | |
| -1 | 33,567,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 271 | 1,355 | 1,897 | 3,539 | 9,485 | 17,695 | 24,773 | 123,865 | 959,069 | 4,795,345 | 6,713,483 | 33,567,415 |
| -1 | -5 | -7 | -35 | -271 | -1,355 | -1,897 | -3,539 | -9,485 | -17,695 | -24,773 | -123,865 | -959,069 | -4,795,345 | -6,713,483 | -33,567,415 |
