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 178,957,235, 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 | 178,957,235 | |
| -1 | -178,957,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 178,957,235.
Example:
1 x 178,957,235 = 178,957,235
and
-1 x -178,957,235 = 178,957,235
Notice both answers equal 178,957,235
With that explanation out of the way, let's continue. Next, we take the number 178,957,235 and divide it by 2:
178,957,235 ÷ 2 = 89,478,617.5
If the quotient is a whole number, then 2 and 89,478,617.5 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 | 178,957,235 | |
| -1 | -178,957,235 |
Now, we try dividing 178,957,235 by 3:
178,957,235 ÷ 3 = 59,652,411.6667
If the quotient is a whole number, then 3 and 59,652,411.6667 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 | 178,957,235 | |
| -1 | -178,957,235 |
Let's try dividing by 4:
178,957,235 ÷ 4 = 44,739,308.75
If the quotient is a whole number, then 4 and 44,739,308.75 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 | 178,957,235 | |
| -1 | 178,957,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 157 | 277 | 785 | 823 | 1,385 | 4,115 | 43,489 | 129,211 | 217,445 | 227,971 | 646,055 | 1,139,855 | 35,791,447 | 178,957,235 |
| -1 | -5 | -157 | -277 | -785 | -823 | -1,385 | -4,115 | -43,489 | -129,211 | -217,445 | -227,971 | -646,055 | -1,139,855 | -35,791,447 | -178,957,235 |
