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 228,505,631, 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 | 228,505,631 | |
| -1 | -228,505,631 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 228,505,631.
Example:
1 x 228,505,631 = 228,505,631
and
-1 x -228,505,631 = 228,505,631
Notice both answers equal 228,505,631
With that explanation out of the way, let's continue. Next, we take the number 228,505,631 and divide it by 2:
228,505,631 ÷ 2 = 114,252,815.5
If the quotient is a whole number, then 2 and 114,252,815.5 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 | 228,505,631 | |
| -1 | -228,505,631 |
Now, we try dividing 228,505,631 by 3:
228,505,631 ÷ 3 = 76,168,543.6667
If the quotient is a whole number, then 3 and 76,168,543.6667 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 | 228,505,631 | |
| -1 | -228,505,631 |
Let's try dividing by 4:
228,505,631 ÷ 4 = 57,126,407.75
If the quotient is a whole number, then 4 and 57,126,407.75 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 | 228,505,631 | |
| -1 | 228,505,631 |
If you did it right, you will end up with this table:
| 1 | 53 | 89 | 193 | 251 | 4,717 | 10,229 | 13,303 | 17,177 | 22,339 | 48,443 | 910,381 | 1,183,967 | 2,567,479 | 4,311,427 | 228,505,631 |
| -1 | -53 | -89 | -193 | -251 | -4,717 | -10,229 | -13,303 | -17,177 | -22,339 | -48,443 | -910,381 | -1,183,967 | -2,567,479 | -4,311,427 | -228,505,631 |
