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 202,426,055, 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 | 202,426,055 | |
| -1 | -202,426,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 202,426,055.
Example:
1 x 202,426,055 = 202,426,055
and
-1 x -202,426,055 = 202,426,055
Notice both answers equal 202,426,055
With that explanation out of the way, let's continue. Next, we take the number 202,426,055 and divide it by 2:
202,426,055 ÷ 2 = 101,213,027.5
If the quotient is a whole number, then 2 and 101,213,027.5 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 | 202,426,055 | |
| -1 | -202,426,055 |
Now, we try dividing 202,426,055 by 3:
202,426,055 ÷ 3 = 67,475,351.6667
If the quotient is a whole number, then 3 and 67,475,351.6667 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 | 202,426,055 | |
| -1 | -202,426,055 |
Let's try dividing by 4:
202,426,055 ÷ 4 = 50,606,513.75
If the quotient is a whole number, then 4 and 50,606,513.75 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 | 202,426,055 | |
| -1 | 202,426,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 221 | 1,105 | 183,191 | 915,955 | 2,381,483 | 3,114,247 | 11,907,415 | 15,571,235 | 40,485,211 | 202,426,055 |
| -1 | -5 | -13 | -17 | -65 | -85 | -221 | -1,105 | -183,191 | -915,955 | -2,381,483 | -3,114,247 | -11,907,415 | -15,571,235 | -40,485,211 | -202,426,055 |
