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 220,211,201, 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 | 220,211,201 | |
| -1 | -220,211,201 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 220,211,201.
Example:
1 x 220,211,201 = 220,211,201
and
-1 x -220,211,201 = 220,211,201
Notice both answers equal 220,211,201
With that explanation out of the way, let's continue. Next, we take the number 220,211,201 and divide it by 2:
220,211,201 ÷ 2 = 110,105,600.5
If the quotient is a whole number, then 2 and 110,105,600.5 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 | 220,211,201 | |
| -1 | -220,211,201 |
Now, we try dividing 220,211,201 by 3:
220,211,201 ÷ 3 = 73,403,733.6667
If the quotient is a whole number, then 3 and 73,403,733.6667 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 | 220,211,201 | |
| -1 | -220,211,201 |
Let's try dividing by 4:
220,211,201 ÷ 4 = 55,052,800.25
If the quotient is a whole number, then 4 and 55,052,800.25 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 | 220,211,201 | |
| -1 | 220,211,201 |
If you did it right, you will end up with this table:
| 1 | 7 | 83 | 269 | 581 | 1,409 | 1,883 | 9,863 | 22,327 | 116,947 | 156,289 | 379,021 | 818,629 | 2,653,147 | 31,458,743 | 220,211,201 |
| -1 | -7 | -83 | -269 | -581 | -1,409 | -1,883 | -9,863 | -22,327 | -116,947 | -156,289 | -379,021 | -818,629 | -2,653,147 | -31,458,743 | -220,211,201 |
