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 166,698,935, 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 | 166,698,935 | |
| -1 | -166,698,935 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,698,935.
Example:
1 x 166,698,935 = 166,698,935
and
-1 x -166,698,935 = 166,698,935
Notice both answers equal 166,698,935
With that explanation out of the way, let's continue. Next, we take the number 166,698,935 and divide it by 2:
166,698,935 ÷ 2 = 83,349,467.5
If the quotient is a whole number, then 2 and 83,349,467.5 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 | 166,698,935 | |
| -1 | -166,698,935 |
Now, we try dividing 166,698,935 by 3:
166,698,935 ÷ 3 = 55,566,311.6667
If the quotient is a whole number, then 3 and 55,566,311.6667 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 | 166,698,935 | |
| -1 | -166,698,935 |
Let's try dividing by 4:
166,698,935 ÷ 4 = 41,674,733.75
If the quotient is a whole number, then 4 and 41,674,733.75 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 | 166,698,935 | |
| -1 | 166,698,935 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 31 | 65 | 155 | 403 | 2,015 | 82,729 | 413,645 | 1,075,477 | 2,564,599 | 5,377,385 | 12,822,995 | 33,339,787 | 166,698,935 |
| -1 | -5 | -13 | -31 | -65 | -155 | -403 | -2,015 | -82,729 | -413,645 | -1,075,477 | -2,564,599 | -5,377,385 | -12,822,995 | -33,339,787 | -166,698,935 |
