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 203,312,305, 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 | 203,312,305 | |
| -1 | -203,312,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 203,312,305.
Example:
1 x 203,312,305 = 203,312,305
and
-1 x -203,312,305 = 203,312,305
Notice both answers equal 203,312,305
With that explanation out of the way, let's continue. Next, we take the number 203,312,305 and divide it by 2:
203,312,305 ÷ 2 = 101,656,152.5
If the quotient is a whole number, then 2 and 101,656,152.5 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 | 203,312,305 | |
| -1 | -203,312,305 |
Now, we try dividing 203,312,305 by 3:
203,312,305 ÷ 3 = 67,770,768.3333
If the quotient is a whole number, then 3 and 67,770,768.3333 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 | 203,312,305 | |
| -1 | -203,312,305 |
Let's try dividing by 4:
203,312,305 ÷ 4 = 50,828,076.25
If the quotient is a whole number, then 4 and 50,828,076.25 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 | 203,312,305 | |
| -1 | 203,312,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 107 | 233 | 535 | 749 | 1,165 | 1,631 | 3,745 | 8,155 | 24,931 | 54,289 | 124,655 | 174,517 | 271,445 | 380,023 | 872,585 | 1,900,115 | 5,808,923 | 29,044,615 | 40,662,461 | 203,312,305 |
| -1 | -5 | -7 | -35 | -107 | -233 | -535 | -749 | -1,165 | -1,631 | -3,745 | -8,155 | -24,931 | -54,289 | -124,655 | -174,517 | -271,445 | -380,023 | -872,585 | -1,900,115 | -5,808,923 | -29,044,615 | -40,662,461 | -203,312,305 |
