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 220,200,235, 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 | 220,200,235 | |
| -1 | -220,200,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 220,200,235.
Example:
1 x 220,200,235 = 220,200,235
and
-1 x -220,200,235 = 220,200,235
Notice both answers equal 220,200,235
With that explanation out of the way, let's continue. Next, we take the number 220,200,235 and divide it by 2:
220,200,235 ÷ 2 = 110,100,117.5
If the quotient is a whole number, then 2 and 110,100,117.5 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 | 220,200,235 | |
| -1 | -220,200,235 |
Now, we try dividing 220,200,235 by 3:
220,200,235 ÷ 3 = 73,400,078.3333
If the quotient is a whole number, then 3 and 73,400,078.3333 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 | 220,200,235 | |
| -1 | -220,200,235 |
Let's try dividing by 4:
220,200,235 ÷ 4 = 55,050,058.75
If the quotient is a whole number, then 4 and 55,050,058.75 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 | 220,200,235 | |
| -1 | 220,200,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 223 | 1,115 | 3,791 | 11,617 | 18,955 | 58,085 | 197,489 | 987,445 | 2,590,591 | 12,952,955 | 44,040,047 | 220,200,235 |
| -1 | -5 | -17 | -85 | -223 | -1,115 | -3,791 | -11,617 | -18,955 | -58,085 | -197,489 | -987,445 | -2,590,591 | -12,952,955 | -44,040,047 | -220,200,235 |
