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 203,472,635, 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 | 203,472,635 | |
| -1 | -203,472,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 203,472,635.
Example:
1 x 203,472,635 = 203,472,635
and
-1 x -203,472,635 = 203,472,635
Notice both answers equal 203,472,635
With that explanation out of the way, let's continue. Next, we take the number 203,472,635 and divide it by 2:
203,472,635 ÷ 2 = 101,736,317.5
If the quotient is a whole number, then 2 and 101,736,317.5 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 | 203,472,635 | |
| -1 | -203,472,635 |
Now, we try dividing 203,472,635 by 3:
203,472,635 ÷ 3 = 67,824,211.6667
If the quotient is a whole number, then 3 and 67,824,211.6667 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 | 203,472,635 | |
| -1 | -203,472,635 |
Let's try dividing by 4:
203,472,635 ÷ 4 = 50,868,158.75
If the quotient is a whole number, then 4 and 50,868,158.75 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 | 203,472,635 | |
| -1 | 203,472,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 67 | 235 | 335 | 3,149 | 12,923 | 15,745 | 64,615 | 607,381 | 865,841 | 3,036,905 | 4,329,205 | 40,694,527 | 203,472,635 |
| -1 | -5 | -47 | -67 | -235 | -335 | -3,149 | -12,923 | -15,745 | -64,615 | -607,381 | -865,841 | -3,036,905 | -4,329,205 | -40,694,527 | -203,472,635 |
