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 660,502,201, 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 | 660,502,201 | |
| -1 | -660,502,201 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 660,502,201.
Example:
1 x 660,502,201 = 660,502,201
and
-1 x -660,502,201 = 660,502,201
Notice both answers equal 660,502,201
With that explanation out of the way, let's continue. Next, we take the number 660,502,201 and divide it by 2:
660,502,201 ÷ 2 = 330,251,100.5
If the quotient is a whole number, then 2 and 330,251,100.5 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 | 660,502,201 | |
| -1 | -660,502,201 |
Now, we try dividing 660,502,201 by 3:
660,502,201 ÷ 3 = 220,167,400.3333
If the quotient is a whole number, then 3 and 220,167,400.3333 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 | 660,502,201 | |
| -1 | -660,502,201 |
Let's try dividing by 4:
660,502,201 ÷ 4 = 165,125,550.25
If the quotient is a whole number, then 4 and 165,125,550.25 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 | 660,502,201 | |
| -1 | 660,502,201 |
If you did it right, you will end up with this table:
| 1 | 23 | 167 | 359 | 479 | 3,841 | 8,257 | 11,017 | 59,953 | 79,993 | 171,961 | 1,378,919 | 1,839,839 | 3,955,103 | 28,717,487 | 660,502,201 |
| -1 | -23 | -167 | -359 | -479 | -3,841 | -8,257 | -11,017 | -59,953 | -79,993 | -171,961 | -1,378,919 | -1,839,839 | -3,955,103 | -28,717,487 | -660,502,201 |
