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 203,222,005, 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 | 203,222,005 | |
| -1 | -203,222,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 203,222,005.
Example:
1 x 203,222,005 = 203,222,005
and
-1 x -203,222,005 = 203,222,005
Notice both answers equal 203,222,005
With that explanation out of the way, let's continue. Next, we take the number 203,222,005 and divide it by 2:
203,222,005 ÷ 2 = 101,611,002.5
If the quotient is a whole number, then 2 and 101,611,002.5 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 | 203,222,005 | |
| -1 | -203,222,005 |
Now, we try dividing 203,222,005 by 3:
203,222,005 ÷ 3 = 67,740,668.3333
If the quotient is a whole number, then 3 and 67,740,668.3333 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 | 203,222,005 | |
| -1 | -203,222,005 |
Let's try dividing by 4:
203,222,005 ÷ 4 = 50,805,501.25
If the quotient is a whole number, then 4 and 50,805,501.25 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 | 203,222,005 | |
| -1 | 203,222,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 305,597 | 1,527,985 | 2,139,179 | 5,806,343 | 10,695,895 | 29,031,715 | 40,644,401 | 203,222,005 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -305,597 | -1,527,985 | -2,139,179 | -5,806,343 | -10,695,895 | -29,031,715 | -40,644,401 | -203,222,005 |
