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 228,333,581, 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 | 228,333,581 | |
| -1 | -228,333,581 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 228,333,581.
Example:
1 x 228,333,581 = 228,333,581
and
-1 x -228,333,581 = 228,333,581
Notice both answers equal 228,333,581
With that explanation out of the way, let's continue. Next, we take the number 228,333,581 and divide it by 2:
228,333,581 ÷ 2 = 114,166,790.5
If the quotient is a whole number, then 2 and 114,166,790.5 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 | 228,333,581 | |
| -1 | -228,333,581 |
Now, we try dividing 228,333,581 by 3:
228,333,581 ÷ 3 = 76,111,193.6667
If the quotient is a whole number, then 3 and 76,111,193.6667 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 | 228,333,581 | |
| -1 | -228,333,581 |
Let's try dividing by 4:
228,333,581 ÷ 4 = 57,083,395.25
If the quotient is a whole number, then 4 and 57,083,395.25 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 | 228,333,581 | |
| -1 | 228,333,581 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 49 | 83 | 161 | 581 | 1,127 | 1,909 | 2,441 | 4,067 | 13,363 | 17,087 | 56,143 | 93,541 | 119,609 | 202,603 | 393,001 | 1,418,221 | 2,751,007 | 4,659,869 | 9,927,547 | 32,619,083 | 228,333,581 |
| -1 | -7 | -23 | -49 | -83 | -161 | -581 | -1,127 | -1,909 | -2,441 | -4,067 | -13,363 | -17,087 | -56,143 | -93,541 | -119,609 | -202,603 | -393,001 | -1,418,221 | -2,751,007 | -4,659,869 | -9,927,547 | -32,619,083 | -228,333,581 |
