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 203,253,355, 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 | 203,253,355 | |
| -1 | -203,253,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 203,253,355.
Example:
1 x 203,253,355 = 203,253,355
and
-1 x -203,253,355 = 203,253,355
Notice both answers equal 203,253,355
With that explanation out of the way, let's continue. Next, we take the number 203,253,355 and divide it by 2:
203,253,355 ÷ 2 = 101,626,677.5
If the quotient is a whole number, then 2 and 101,626,677.5 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 | 203,253,355 | |
| -1 | -203,253,355 |
Now, we try dividing 203,253,355 by 3:
203,253,355 ÷ 3 = 67,751,118.3333
If the quotient is a whole number, then 3 and 67,751,118.3333 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 | 203,253,355 | |
| -1 | -203,253,355 |
Let's try dividing by 4:
203,253,355 ÷ 4 = 50,813,338.75
If the quotient is a whole number, then 4 and 50,813,338.75 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 | 203,253,355 | |
| -1 | 203,253,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 883 | 2,423 | 4,415 | 12,115 | 16,777 | 46,037 | 83,885 | 230,185 | 2,139,509 | 10,697,545 | 40,650,671 | 203,253,355 |
| -1 | -5 | -19 | -95 | -883 | -2,423 | -4,415 | -12,115 | -16,777 | -46,037 | -83,885 | -230,185 | -2,139,509 | -10,697,545 | -40,650,671 | -203,253,355 |
