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 201,562,097, 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 | 201,562,097 | |
| -1 | -201,562,097 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 201,562,097.
Example:
1 x 201,562,097 = 201,562,097
and
-1 x -201,562,097 = 201,562,097
Notice both answers equal 201,562,097
With that explanation out of the way, let's continue. Next, we take the number 201,562,097 and divide it by 2:
201,562,097 ÷ 2 = 100,781,048.5
If the quotient is a whole number, then 2 and 100,781,048.5 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 | 201,562,097 | |
| -1 | -201,562,097 |
Now, we try dividing 201,562,097 by 3:
201,562,097 ÷ 3 = 67,187,365.6667
If the quotient is a whole number, then 3 and 67,187,365.6667 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 | 201,562,097 | |
| -1 | -201,562,097 |
Let's try dividing by 4:
201,562,097 ÷ 4 = 50,390,524.25
If the quotient is a whole number, then 4 and 50,390,524.25 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 | 201,562,097 | |
| -1 | 201,562,097 |
If you did it right, you will end up with this table:
| 1 | 11 | 83 | 277 | 797 | 913 | 3,047 | 8,767 | 22,991 | 66,151 | 220,769 | 252,901 | 727,661 | 2,428,459 | 18,323,827 | 201,562,097 |
| -1 | -11 | -83 | -277 | -797 | -913 | -3,047 | -8,767 | -22,991 | -66,151 | -220,769 | -252,901 | -727,661 | -2,428,459 | -18,323,827 | -201,562,097 |
