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 220,544,533, 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 | 220,544,533 | |
| -1 | -220,544,533 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 220,544,533.
Example:
1 x 220,544,533 = 220,544,533
and
-1 x -220,544,533 = 220,544,533
Notice both answers equal 220,544,533
With that explanation out of the way, let's continue. Next, we take the number 220,544,533 and divide it by 2:
220,544,533 ÷ 2 = 110,272,266.5
If the quotient is a whole number, then 2 and 110,272,266.5 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 | 220,544,533 | |
| -1 | -220,544,533 |
Now, we try dividing 220,544,533 by 3:
220,544,533 ÷ 3 = 73,514,844.3333
If the quotient is a whole number, then 3 and 73,514,844.3333 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 | 220,544,533 | |
| -1 | -220,544,533 |
Let's try dividing by 4:
220,544,533 ÷ 4 = 55,136,133.25
If the quotient is a whole number, then 4 and 55,136,133.25 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 | 220,544,533 | |
| -1 | 220,544,533 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 209 | 479 | 2,203 | 5,269 | 9,101 | 24,233 | 41,857 | 100,111 | 460,427 | 1,055,237 | 11,607,607 | 20,049,503 | 220,544,533 |
| -1 | -11 | -19 | -209 | -479 | -2,203 | -5,269 | -9,101 | -24,233 | -41,857 | -100,111 | -460,427 | -1,055,237 | -11,607,607 | -20,049,503 | -220,544,533 |
