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 228,201,455, 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 | 228,201,455 | |
| -1 | -228,201,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 228,201,455.
Example:
1 x 228,201,455 = 228,201,455
and
-1 x -228,201,455 = 228,201,455
Notice both answers equal 228,201,455
With that explanation out of the way, let's continue. Next, we take the number 228,201,455 and divide it by 2:
228,201,455 ÷ 2 = 114,100,727.5
If the quotient is a whole number, then 2 and 114,100,727.5 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 | 228,201,455 | |
| -1 | -228,201,455 |
Now, we try dividing 228,201,455 by 3:
228,201,455 ÷ 3 = 76,067,151.6667
If the quotient is a whole number, then 3 and 76,067,151.6667 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 | 228,201,455 | |
| -1 | -228,201,455 |
Let's try dividing by 4:
228,201,455 ÷ 4 = 57,050,363.75
If the quotient is a whole number, then 4 and 57,050,363.75 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 | 228,201,455 | |
| -1 | 228,201,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 71 | 85 | 355 | 1,207 | 6,035 | 37,813 | 189,065 | 642,821 | 2,684,723 | 3,214,105 | 13,423,615 | 45,640,291 | 228,201,455 |
| -1 | -5 | -17 | -71 | -85 | -355 | -1,207 | -6,035 | -37,813 | -189,065 | -642,821 | -2,684,723 | -3,214,105 | -13,423,615 | -45,640,291 | -228,201,455 |
