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 228,318,815, 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 | 228,318,815 | |
| -1 | -228,318,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 228,318,815.
Example:
1 x 228,318,815 = 228,318,815
and
-1 x -228,318,815 = 228,318,815
Notice both answers equal 228,318,815
With that explanation out of the way, let's continue. Next, we take the number 228,318,815 and divide it by 2:
228,318,815 ÷ 2 = 114,159,407.5
If the quotient is a whole number, then 2 and 114,159,407.5 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 | 228,318,815 | |
| -1 | -228,318,815 |
Now, we try dividing 228,318,815 by 3:
228,318,815 ÷ 3 = 76,106,271.6667
If the quotient is a whole number, then 3 and 76,106,271.6667 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 | 228,318,815 | |
| -1 | -228,318,815 |
Let's try dividing by 4:
228,318,815 ÷ 4 = 57,079,703.75
If the quotient is a whole number, then 4 and 57,079,703.75 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 | 228,318,815 | |
| -1 | 228,318,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 73 | 115 | 365 | 1,679 | 8,395 | 27,197 | 135,985 | 625,531 | 1,985,381 | 3,127,655 | 9,926,905 | 45,663,763 | 228,318,815 |
| -1 | -5 | -23 | -73 | -115 | -365 | -1,679 | -8,395 | -27,197 | -135,985 | -625,531 | -1,985,381 | -3,127,655 | -9,926,905 | -45,663,763 | -228,318,815 |
