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 66,433,535, 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 | 66,433,535 | |
| -1 | -66,433,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 66,433,535.
Example:
1 x 66,433,535 = 66,433,535
and
-1 x -66,433,535 = 66,433,535
Notice both answers equal 66,433,535
With that explanation out of the way, let's continue. Next, we take the number 66,433,535 and divide it by 2:
66,433,535 ÷ 2 = 33,216,767.5
If the quotient is a whole number, then 2 and 33,216,767.5 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 | 66,433,535 | |
| -1 | -66,433,535 |
Now, we try dividing 66,433,535 by 3:
66,433,535 ÷ 3 = 22,144,511.6667
If the quotient is a whole number, then 3 and 22,144,511.6667 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 | 66,433,535 | |
| -1 | -66,433,535 |
Let's try dividing by 4:
66,433,535 ÷ 4 = 16,608,383.75
If the quotient is a whole number, then 4 and 16,608,383.75 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 | 66,433,535 | |
| -1 | 66,433,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 111,653 | 558,265 | 781,571 | 1,898,101 | 3,907,855 | 9,490,505 | 13,286,707 | 66,433,535 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -111,653 | -558,265 | -781,571 | -1,898,101 | -3,907,855 | -9,490,505 | -13,286,707 | -66,433,535 |
