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 220,033,567, 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 | 220,033,567 | |
| -1 | -220,033,567 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 220,033,567.
Example:
1 x 220,033,567 = 220,033,567
and
-1 x -220,033,567 = 220,033,567
Notice both answers equal 220,033,567
With that explanation out of the way, let's continue. Next, we take the number 220,033,567 and divide it by 2:
220,033,567 ÷ 2 = 110,016,783.5
If the quotient is a whole number, then 2 and 110,016,783.5 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 | 220,033,567 | |
| -1 | -220,033,567 |
Now, we try dividing 220,033,567 by 3:
220,033,567 ÷ 3 = 73,344,522.3333
If the quotient is a whole number, then 3 and 73,344,522.3333 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 | 220,033,567 | |
| -1 | -220,033,567 |
Let's try dividing by 4:
220,033,567 ÷ 4 = 55,008,391.75
If the quotient is a whole number, then 4 and 55,008,391.75 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 | 220,033,567 | |
| -1 | 220,033,567 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 31 | 221 | 403 | 527 | 6,851 | 32,117 | 417,521 | 545,989 | 995,627 | 7,097,857 | 12,943,151 | 16,925,659 | 220,033,567 |
| -1 | -13 | -17 | -31 | -221 | -403 | -527 | -6,851 | -32,117 | -417,521 | -545,989 | -995,627 | -7,097,857 | -12,943,151 | -16,925,659 | -220,033,567 |
