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 220,030,213, 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 | 220,030,213 | |
| -1 | -220,030,213 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 220,030,213.
Example:
1 x 220,030,213 = 220,030,213
and
-1 x -220,030,213 = 220,030,213
Notice both answers equal 220,030,213
With that explanation out of the way, let's continue. Next, we take the number 220,030,213 and divide it by 2:
220,030,213 ÷ 2 = 110,015,106.5
If the quotient is a whole number, then 2 and 110,015,106.5 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 | 220,030,213 | |
| -1 | -220,030,213 |
Now, we try dividing 220,030,213 by 3:
220,030,213 ÷ 3 = 73,343,404.3333
If the quotient is a whole number, then 3 and 73,343,404.3333 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 | 220,030,213 | |
| -1 | -220,030,213 |
Let's try dividing by 4:
220,030,213 ÷ 4 = 55,007,553.25
If the quotient is a whole number, then 4 and 55,007,553.25 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 | 220,030,213 | |
| -1 | 220,030,213 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 299 | 761 | 967 | 9,893 | 12,571 | 17,503 | 22,241 | 227,539 | 289,133 | 735,887 | 9,566,531 | 16,925,401 | 220,030,213 |
| -1 | -13 | -23 | -299 | -761 | -967 | -9,893 | -12,571 | -17,503 | -22,241 | -227,539 | -289,133 | -735,887 | -9,566,531 | -16,925,401 | -220,030,213 |
