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 433,716,655, 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 | 433,716,655 | |
| -1 | -433,716,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 433,716,655.
Example:
1 x 433,716,655 = 433,716,655
and
-1 x -433,716,655 = 433,716,655
Notice both answers equal 433,716,655
With that explanation out of the way, let's continue. Next, we take the number 433,716,655 and divide it by 2:
433,716,655 ÷ 2 = 216,858,327.5
If the quotient is a whole number, then 2 and 216,858,327.5 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 | 433,716,655 | |
| -1 | -433,716,655 |
Now, we try dividing 433,716,655 by 3:
433,716,655 ÷ 3 = 144,572,218.3333
If the quotient is a whole number, then 3 and 144,572,218.3333 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 | 433,716,655 | |
| -1 | -433,716,655 |
Let's try dividing by 4:
433,716,655 ÷ 4 = 108,429,163.75
If the quotient is a whole number, then 4 and 108,429,163.75 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 | 433,716,655 | |
| -1 | 433,716,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 137 | 205 | 685 | 5,617 | 15,443 | 28,085 | 77,215 | 633,163 | 2,115,691 | 3,165,815 | 10,578,455 | 86,743,331 | 433,716,655 |
| -1 | -5 | -41 | -137 | -205 | -685 | -5,617 | -15,443 | -28,085 | -77,215 | -633,163 | -2,115,691 | -3,165,815 | -10,578,455 | -86,743,331 | -433,716,655 |
