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 185,176,835, 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 | 185,176,835 | |
| -1 | -185,176,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 185,176,835.
Example:
1 x 185,176,835 = 185,176,835
and
-1 x -185,176,835 = 185,176,835
Notice both answers equal 185,176,835
With that explanation out of the way, let's continue. Next, we take the number 185,176,835 and divide it by 2:
185,176,835 ÷ 2 = 92,588,417.5
If the quotient is a whole number, then 2 and 92,588,417.5 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 | 185,176,835 | |
| -1 | -185,176,835 |
Now, we try dividing 185,176,835 by 3:
185,176,835 ÷ 3 = 61,725,611.6667
If the quotient is a whole number, then 3 and 61,725,611.6667 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 | 185,176,835 | |
| -1 | -185,176,835 |
Let's try dividing by 4:
185,176,835 ÷ 4 = 46,294,208.75
If the quotient is a whole number, then 4 and 46,294,208.75 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 | 185,176,835 | |
| -1 | 185,176,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 1,471 | 1,481 | 7,355 | 7,405 | 25,007 | 25,177 | 125,035 | 125,885 | 2,178,551 | 10,892,755 | 37,035,367 | 185,176,835 |
| -1 | -5 | -17 | -85 | -1,471 | -1,481 | -7,355 | -7,405 | -25,007 | -25,177 | -125,035 | -125,885 | -2,178,551 | -10,892,755 | -37,035,367 | -185,176,835 |
