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 33,070,807, 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 | 33,070,807 | |
| -1 | -33,070,807 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,070,807.
Example:
1 x 33,070,807 = 33,070,807
and
-1 x -33,070,807 = 33,070,807
Notice both answers equal 33,070,807
With that explanation out of the way, let's continue. Next, we take the number 33,070,807 and divide it by 2:
33,070,807 ÷ 2 = 16,535,403.5
If the quotient is a whole number, then 2 and 16,535,403.5 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 | 33,070,807 | |
| -1 | -33,070,807 |
Now, we try dividing 33,070,807 by 3:
33,070,807 ÷ 3 = 11,023,602.3333
If the quotient is a whole number, then 3 and 11,023,602.3333 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 | 33,070,807 | |
| -1 | -33,070,807 |
Let's try dividing by 4:
33,070,807 ÷ 4 = 8,267,701.75
If the quotient is a whole number, then 4 and 8,267,701.75 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 | 33,070,807 | |
| -1 | 33,070,807 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 311 | 1,381 | 2,177 | 3,421 | 9,667 | 15,191 | 23,947 | 106,337 | 429,491 | 3,006,437 | 4,724,401 | 33,070,807 |
| -1 | -7 | -11 | -77 | -311 | -1,381 | -2,177 | -3,421 | -9,667 | -15,191 | -23,947 | -106,337 | -429,491 | -3,006,437 | -4,724,401 | -33,070,807 |
