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 166,056,163, 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 | 166,056,163 | |
| -1 | -166,056,163 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,056,163.
Example:
1 x 166,056,163 = 166,056,163
and
-1 x -166,056,163 = 166,056,163
Notice both answers equal 166,056,163
With that explanation out of the way, let's continue. Next, we take the number 166,056,163 and divide it by 2:
166,056,163 ÷ 2 = 83,028,081.5
If the quotient is a whole number, then 2 and 83,028,081.5 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 | 166,056,163 | |
| -1 | -166,056,163 |
Now, we try dividing 166,056,163 by 3:
166,056,163 ÷ 3 = 55,352,054.3333
If the quotient is a whole number, then 3 and 55,352,054.3333 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 | 166,056,163 | |
| -1 | -166,056,163 |
Let's try dividing by 4:
166,056,163 ÷ 4 = 41,514,040.75
If the quotient is a whole number, then 4 and 41,514,040.75 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 | 166,056,163 | |
| -1 | 166,056,163 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 541 | 3,373 | 3,787 | 7,033 | 23,611 | 43,849 | 49,231 | 306,943 | 1,824,793 | 12,773,551 | 23,722,309 | 166,056,163 |
| -1 | -7 | -13 | -91 | -541 | -3,373 | -3,787 | -7,033 | -23,611 | -43,849 | -49,231 | -306,943 | -1,824,793 | -12,773,551 | -23,722,309 | -166,056,163 |
