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 220,545,335, 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 | 220,545,335 | |
| -1 | -220,545,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 220,545,335.
Example:
1 x 220,545,335 = 220,545,335
and
-1 x -220,545,335 = 220,545,335
Notice both answers equal 220,545,335
With that explanation out of the way, let's continue. Next, we take the number 220,545,335 and divide it by 2:
220,545,335 ÷ 2 = 110,272,667.5
If the quotient is a whole number, then 2 and 110,272,667.5 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 | 220,545,335 | |
| -1 | -220,545,335 |
Now, we try dividing 220,545,335 by 3:
220,545,335 ÷ 3 = 73,515,111.6667
If the quotient is a whole number, then 3 and 73,515,111.6667 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 | 220,545,335 | |
| -1 | -220,545,335 |
Let's try dividing by 4:
220,545,335 ÷ 4 = 55,136,333.75
If the quotient is a whole number, then 4 and 55,136,333.75 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 | 220,545,335 | |
| -1 | 220,545,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 443 | 2,215 | 5,857 | 7,531 | 29,285 | 37,655 | 99,569 | 497,845 | 2,594,651 | 12,973,255 | 44,109,067 | 220,545,335 |
| -1 | -5 | -17 | -85 | -443 | -2,215 | -5,857 | -7,531 | -29,285 | -37,655 | -99,569 | -497,845 | -2,594,651 | -12,973,255 | -44,109,067 | -220,545,335 |
