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 203,571,035, 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 | 203,571,035 | |
| -1 | -203,571,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 203,571,035.
Example:
1 x 203,571,035 = 203,571,035
and
-1 x -203,571,035 = 203,571,035
Notice both answers equal 203,571,035
With that explanation out of the way, let's continue. Next, we take the number 203,571,035 and divide it by 2:
203,571,035 ÷ 2 = 101,785,517.5
If the quotient is a whole number, then 2 and 101,785,517.5 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 | 203,571,035 | |
| -1 | -203,571,035 |
Now, we try dividing 203,571,035 by 3:
203,571,035 ÷ 3 = 67,857,011.6667
If the quotient is a whole number, then 3 and 67,857,011.6667 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 | 203,571,035 | |
| -1 | -203,571,035 |
Let's try dividing by 4:
203,571,035 ÷ 4 = 50,892,758.75
If the quotient is a whole number, then 4 and 50,892,758.75 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 | 203,571,035 | |
| -1 | 203,571,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 89 | 95 | 445 | 1,691 | 8,455 | 24,077 | 120,385 | 457,463 | 2,142,853 | 2,287,315 | 10,714,265 | 40,714,207 | 203,571,035 |
| -1 | -5 | -19 | -89 | -95 | -445 | -1,691 | -8,455 | -24,077 | -120,385 | -457,463 | -2,142,853 | -2,287,315 | -10,714,265 | -40,714,207 | -203,571,035 |
