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 201,671,063, 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 | 201,671,063 | |
| -1 | -201,671,063 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 201,671,063.
Example:
1 x 201,671,063 = 201,671,063
and
-1 x -201,671,063 = 201,671,063
Notice both answers equal 201,671,063
With that explanation out of the way, let's continue. Next, we take the number 201,671,063 and divide it by 2:
201,671,063 ÷ 2 = 100,835,531.5
If the quotient is a whole number, then 2 and 100,835,531.5 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 | 201,671,063 | |
| -1 | -201,671,063 |
Now, we try dividing 201,671,063 by 3:
201,671,063 ÷ 3 = 67,223,687.6667
If the quotient is a whole number, then 3 and 67,223,687.6667 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 | 201,671,063 | |
| -1 | -201,671,063 |
Let's try dividing by 4:
201,671,063 ÷ 4 = 50,417,765.75
If the quotient is a whole number, then 4 and 50,417,765.75 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 | 201,671,063 | |
| -1 | 201,671,063 |
If you did it right, you will end up with this table:
| 1 | 11 | 61 | 89 | 121 | 307 | 671 | 979 | 3,377 | 5,429 | 7,381 | 10,769 | 18,727 | 27,323 | 37,147 | 59,719 | 205,997 | 300,553 | 656,909 | 1,666,703 | 2,265,967 | 3,306,083 | 18,333,733 | 201,671,063 |
| -1 | -11 | -61 | -89 | -121 | -307 | -671 | -979 | -3,377 | -5,429 | -7,381 | -10,769 | -18,727 | -27,323 | -37,147 | -59,719 | -205,997 | -300,553 | -656,909 | -1,666,703 | -2,265,967 | -3,306,083 | -18,333,733 | -201,671,063 |
