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 203,444,137, 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 | 203,444,137 | |
| -1 | -203,444,137 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 203,444,137.
Example:
1 x 203,444,137 = 203,444,137
and
-1 x -203,444,137 = 203,444,137
Notice both answers equal 203,444,137
With that explanation out of the way, let's continue. Next, we take the number 203,444,137 and divide it by 2:
203,444,137 ÷ 2 = 101,722,068.5
If the quotient is a whole number, then 2 and 101,722,068.5 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 | 203,444,137 | |
| -1 | -203,444,137 |
Now, we try dividing 203,444,137 by 3:
203,444,137 ÷ 3 = 67,814,712.3333
If the quotient is a whole number, then 3 and 67,814,712.3333 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 | 203,444,137 | |
| -1 | -203,444,137 |
Let's try dividing by 4:
203,444,137 ÷ 4 = 50,861,034.25
If the quotient is a whole number, then 4 and 50,861,034.25 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 | 203,444,137 | |
| -1 | 203,444,137 |
If you did it right, you will end up with this table:
| 1 | 13 | 43 | 353 | 559 | 1,031 | 4,589 | 13,403 | 15,179 | 44,333 | 197,327 | 363,943 | 576,329 | 4,731,259 | 15,649,549 | 203,444,137 |
| -1 | -13 | -43 | -353 | -559 | -1,031 | -4,589 | -13,403 | -15,179 | -44,333 | -197,327 | -363,943 | -576,329 | -4,731,259 | -15,649,549 | -203,444,137 |
