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 185,658,929, 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 | 185,658,929 | |
| -1 | -185,658,929 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 185,658,929.
Example:
1 x 185,658,929 = 185,658,929
and
-1 x -185,658,929 = 185,658,929
Notice both answers equal 185,658,929
With that explanation out of the way, let's continue. Next, we take the number 185,658,929 and divide it by 2:
185,658,929 ÷ 2 = 92,829,464.5
If the quotient is a whole number, then 2 and 92,829,464.5 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 | 185,658,929 | |
| -1 | -185,658,929 |
Now, we try dividing 185,658,929 by 3:
185,658,929 ÷ 3 = 61,886,309.6667
If the quotient is a whole number, then 3 and 61,886,309.6667 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 | 185,658,929 | |
| -1 | -185,658,929 |
Let's try dividing by 4:
185,658,929 ÷ 4 = 46,414,732.25
If the quotient is a whole number, then 4 and 46,414,732.25 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 | 185,658,929 | |
| -1 | 185,658,929 |
If you did it right, you will end up with this table:
| 1 | 61 | 73 | 173 | 241 | 4,453 | 10,553 | 12,629 | 14,701 | 17,593 | 41,693 | 770,369 | 1,073,173 | 2,543,273 | 3,043,589 | 185,658,929 |
| -1 | -61 | -73 | -173 | -241 | -4,453 | -10,553 | -12,629 | -14,701 | -17,593 | -41,693 | -770,369 | -1,073,173 | -2,543,273 | -3,043,589 | -185,658,929 |
