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 210,050,203, 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 | 210,050,203 | |
| -1 | -210,050,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 210,050,203.
Example:
1 x 210,050,203 = 210,050,203
and
-1 x -210,050,203 = 210,050,203
Notice both answers equal 210,050,203
With that explanation out of the way, let's continue. Next, we take the number 210,050,203 and divide it by 2:
210,050,203 ÷ 2 = 105,025,101.5
If the quotient is a whole number, then 2 and 105,025,101.5 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 | 210,050,203 | |
| -1 | -210,050,203 |
Now, we try dividing 210,050,203 by 3:
210,050,203 ÷ 3 = 70,016,734.3333
If the quotient is a whole number, then 3 and 70,016,734.3333 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 | 210,050,203 | |
| -1 | -210,050,203 |
Let's try dividing by 4:
210,050,203 ÷ 4 = 52,512,550.75
If the quotient is a whole number, then 4 and 52,512,550.75 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 | 210,050,203 | |
| -1 | 210,050,203 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 271 | 341 | 2,273 | 2,981 | 8,401 | 25,003 | 70,463 | 92,411 | 615,983 | 775,093 | 6,775,813 | 19,095,473 | 210,050,203 |
| -1 | -11 | -31 | -271 | -341 | -2,273 | -2,981 | -8,401 | -25,003 | -70,463 | -92,411 | -615,983 | -775,093 | -6,775,813 | -19,095,473 | -210,050,203 |
