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 234,551,155, 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 | 234,551,155 | |
| -1 | -234,551,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 234,551,155.
Example:
1 x 234,551,155 = 234,551,155
and
-1 x -234,551,155 = 234,551,155
Notice both answers equal 234,551,155
With that explanation out of the way, let's continue. Next, we take the number 234,551,155 and divide it by 2:
234,551,155 ÷ 2 = 117,275,577.5
If the quotient is a whole number, then 2 and 117,275,577.5 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 | 234,551,155 | |
| -1 | -234,551,155 |
Now, we try dividing 234,551,155 by 3:
234,551,155 ÷ 3 = 78,183,718.3333
If the quotient is a whole number, then 3 and 78,183,718.3333 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 | 234,551,155 | |
| -1 | -234,551,155 |
Let's try dividing by 4:
234,551,155 ÷ 4 = 58,637,788.75
If the quotient is a whole number, then 4 and 58,637,788.75 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 | 234,551,155 | |
| -1 | 234,551,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 197 | 227 | 985 | 1,049 | 1,135 | 5,245 | 44,719 | 206,653 | 223,595 | 238,123 | 1,033,265 | 1,190,615 | 46,910,231 | 234,551,155 |
| -1 | -5 | -197 | -227 | -985 | -1,049 | -1,135 | -5,245 | -44,719 | -206,653 | -223,595 | -238,123 | -1,033,265 | -1,190,615 | -46,910,231 | -234,551,155 |
