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 228,668,875, 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 | 228,668,875 | |
| -1 | -228,668,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 228,668,875.
Example:
1 x 228,668,875 = 228,668,875
and
-1 x -228,668,875 = 228,668,875
Notice both answers equal 228,668,875
With that explanation out of the way, let's continue. Next, we take the number 228,668,875 and divide it by 2:
228,668,875 ÷ 2 = 114,334,437.5
If the quotient is a whole number, then 2 and 114,334,437.5 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 | 228,668,875 | |
| -1 | -228,668,875 |
Now, we try dividing 228,668,875 by 3:
228,668,875 ÷ 3 = 76,222,958.3333
If the quotient is a whole number, then 3 and 76,222,958.3333 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 | 228,668,875 | |
| -1 | -228,668,875 |
Let's try dividing by 4:
228,668,875 ÷ 4 = 57,167,218.75
If the quotient is a whole number, then 4 and 57,167,218.75 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 | 228,668,875 | |
| -1 | 228,668,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 115 | 125 | 575 | 2,875 | 79,537 | 397,685 | 1,829,351 | 1,988,425 | 9,146,755 | 9,942,125 | 45,733,775 | 228,668,875 |
| -1 | -5 | -23 | -25 | -115 | -125 | -575 | -2,875 | -79,537 | -397,685 | -1,829,351 | -1,988,425 | -9,146,755 | -9,942,125 | -45,733,775 | -228,668,875 |
