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 185,658,935, 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 | 185,658,935 | |
| -1 | -185,658,935 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 185,658,935.
Example:
1 x 185,658,935 = 185,658,935
and
-1 x -185,658,935 = 185,658,935
Notice both answers equal 185,658,935
With that explanation out of the way, let's continue. Next, we take the number 185,658,935 and divide it by 2:
185,658,935 ÷ 2 = 92,829,467.5
If the quotient is a whole number, then 2 and 92,829,467.5 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 | 185,658,935 | |
| -1 | -185,658,935 |
Now, we try dividing 185,658,935 by 3:
185,658,935 ÷ 3 = 61,886,311.6667
If the quotient is a whole number, then 3 and 61,886,311.6667 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 | 185,658,935 | |
| -1 | -185,658,935 |
Let's try dividing by 4:
185,658,935 ÷ 4 = 46,414,733.75
If the quotient is a whole number, then 4 and 46,414,733.75 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 | 185,658,935 | |
| -1 | 185,658,935 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 482,231 | 2,411,155 | 3,375,617 | 5,304,541 | 16,878,085 | 26,522,705 | 37,131,787 | 185,658,935 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -482,231 | -2,411,155 | -3,375,617 | -5,304,541 | -16,878,085 | -26,522,705 | -37,131,787 | -185,658,935 |
