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 201,352,403, 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 | 201,352,403 | |
| -1 | -201,352,403 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 201,352,403.
Example:
1 x 201,352,403 = 201,352,403
and
-1 x -201,352,403 = 201,352,403
Notice both answers equal 201,352,403
With that explanation out of the way, let's continue. Next, we take the number 201,352,403 and divide it by 2:
201,352,403 ÷ 2 = 100,676,201.5
If the quotient is a whole number, then 2 and 100,676,201.5 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 | 201,352,403 | |
| -1 | -201,352,403 |
Now, we try dividing 201,352,403 by 3:
201,352,403 ÷ 3 = 67,117,467.6667
If the quotient is a whole number, then 3 and 67,117,467.6667 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 | 201,352,403 | |
| -1 | -201,352,403 |
Let's try dividing by 4:
201,352,403 ÷ 4 = 50,338,100.75
If the quotient is a whole number, then 4 and 50,338,100.75 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 | 201,352,403 | |
| -1 | 201,352,403 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 1,049 | 1,613 | 7,343 | 11,291 | 17,833 | 27,421 | 124,831 | 191,947 | 1,692,037 | 11,844,259 | 28,764,629 | 201,352,403 |
| -1 | -7 | -17 | -119 | -1,049 | -1,613 | -7,343 | -11,291 | -17,833 | -27,421 | -124,831 | -191,947 | -1,692,037 | -11,844,259 | -28,764,629 | -201,352,403 |
