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 636,323,039, 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 | 636,323,039 | |
| -1 | -636,323,039 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 636,323,039.
Example:
1 x 636,323,039 = 636,323,039
and
-1 x -636,323,039 = 636,323,039
Notice both answers equal 636,323,039
With that explanation out of the way, let's continue. Next, we take the number 636,323,039 and divide it by 2:
636,323,039 ÷ 2 = 318,161,519.5
If the quotient is a whole number, then 2 and 318,161,519.5 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 | 636,323,039 | |
| -1 | -636,323,039 |
Now, we try dividing 636,323,039 by 3:
636,323,039 ÷ 3 = 212,107,679.6667
If the quotient is a whole number, then 3 and 212,107,679.6667 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 | 636,323,039 | |
| -1 | -636,323,039 |
Let's try dividing by 4:
636,323,039 ÷ 4 = 159,080,759.75
If the quotient is a whole number, then 4 and 159,080,759.75 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 | 636,323,039 | |
| -1 | 636,323,039 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 187 | 211 | 2,321 | 3,587 | 16,127 | 39,457 | 177,397 | 274,159 | 3,015,749 | 3,402,797 | 37,430,767 | 57,847,549 | 636,323,039 |
| -1 | -11 | -17 | -187 | -211 | -2,321 | -3,587 | -16,127 | -39,457 | -177,397 | -274,159 | -3,015,749 | -3,402,797 | -37,430,767 | -57,847,549 | -636,323,039 |
