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 166,060,181, 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 | 166,060,181 | |
| -1 | -166,060,181 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,060,181.
Example:
1 x 166,060,181 = 166,060,181
and
-1 x -166,060,181 = 166,060,181
Notice both answers equal 166,060,181
With that explanation out of the way, let's continue. Next, we take the number 166,060,181 and divide it by 2:
166,060,181 ÷ 2 = 83,030,090.5
If the quotient is a whole number, then 2 and 83,030,090.5 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 | 166,060,181 | |
| -1 | -166,060,181 |
Now, we try dividing 166,060,181 by 3:
166,060,181 ÷ 3 = 55,353,393.6667
If the quotient is a whole number, then 3 and 55,353,393.6667 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 | 166,060,181 | |
| -1 | -166,060,181 |
Let's try dividing by 4:
166,060,181 ÷ 4 = 41,515,045.25
If the quotient is a whole number, then 4 and 41,515,045.25 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 | 166,060,181 | |
| -1 | 166,060,181 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 73 | 259 | 511 | 2,701 | 8,783 | 18,907 | 61,481 | 324,971 | 641,159 | 2,274,797 | 4,488,113 | 23,722,883 | 166,060,181 |
| -1 | -7 | -37 | -73 | -259 | -511 | -2,701 | -8,783 | -18,907 | -61,481 | -324,971 | -641,159 | -2,274,797 | -4,488,113 | -23,722,883 | -166,060,181 |
