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 228,906,535, 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 | 228,906,535 | |
| -1 | -228,906,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 228,906,535.
Example:
1 x 228,906,535 = 228,906,535
and
-1 x -228,906,535 = 228,906,535
Notice both answers equal 228,906,535
With that explanation out of the way, let's continue. Next, we take the number 228,906,535 and divide it by 2:
228,906,535 ÷ 2 = 114,453,267.5
If the quotient is a whole number, then 2 and 114,453,267.5 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 | 228,906,535 | |
| -1 | -228,906,535 |
Now, we try dividing 228,906,535 by 3:
228,906,535 ÷ 3 = 76,302,178.3333
If the quotient is a whole number, then 3 and 76,302,178.3333 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 | 228,906,535 | |
| -1 | -228,906,535 |
Let's try dividing by 4:
228,906,535 ÷ 4 = 57,226,633.75
If the quotient is a whole number, then 4 and 57,226,633.75 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 | 228,906,535 | |
| -1 | 228,906,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 715 | 320,149 | 1,600,745 | 3,521,639 | 4,161,937 | 17,608,195 | 20,809,685 | 45,781,307 | 228,906,535 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -715 | -320,149 | -1,600,745 | -3,521,639 | -4,161,937 | -17,608,195 | -20,809,685 | -45,781,307 | -228,906,535 |
