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 201,560,653, 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 | 201,560,653 | |
| -1 | -201,560,653 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 201,560,653.
Example:
1 x 201,560,653 = 201,560,653
and
-1 x -201,560,653 = 201,560,653
Notice both answers equal 201,560,653
With that explanation out of the way, let's continue. Next, we take the number 201,560,653 and divide it by 2:
201,560,653 ÷ 2 = 100,780,326.5
If the quotient is a whole number, then 2 and 100,780,326.5 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 | 201,560,653 | |
| -1 | -201,560,653 |
Now, we try dividing 201,560,653 by 3:
201,560,653 ÷ 3 = 67,186,884.3333
If the quotient is a whole number, then 3 and 67,186,884.3333 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 | 201,560,653 | |
| -1 | -201,560,653 |
Let's try dividing by 4:
201,560,653 ÷ 4 = 50,390,163.25
If the quotient is a whole number, then 4 and 50,390,163.25 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 | 201,560,653 | |
| -1 | 201,560,653 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 61 | 119 | 427 | 1,037 | 7,259 | 27,767 | 194,369 | 472,039 | 1,693,787 | 3,304,273 | 11,856,509 | 28,794,379 | 201,560,653 |
| -1 | -7 | -17 | -61 | -119 | -427 | -1,037 | -7,259 | -27,767 | -194,369 | -472,039 | -1,693,787 | -3,304,273 | -11,856,509 | -28,794,379 | -201,560,653 |
