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 166,654,159, 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 | 166,654,159 | |
| -1 | -166,654,159 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,654,159.
Example:
1 x 166,654,159 = 166,654,159
and
-1 x -166,654,159 = 166,654,159
Notice both answers equal 166,654,159
With that explanation out of the way, let's continue. Next, we take the number 166,654,159 and divide it by 2:
166,654,159 ÷ 2 = 83,327,079.5
If the quotient is a whole number, then 2 and 83,327,079.5 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 | 166,654,159 | |
| -1 | -166,654,159 |
Now, we try dividing 166,654,159 by 3:
166,654,159 ÷ 3 = 55,551,386.3333
If the quotient is a whole number, then 3 and 55,551,386.3333 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 | 166,654,159 | |
| -1 | -166,654,159 |
Let's try dividing by 4:
166,654,159 ÷ 4 = 41,663,539.75
If the quotient is a whole number, then 4 and 41,663,539.75 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 | 166,654,159 | |
| -1 | 166,654,159 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 479 | 2,161 | 3,353 | 11,017 | 15,127 | 49,703 | 77,119 | 347,921 | 1,035,119 | 7,245,833 | 23,807,737 | 166,654,159 |
| -1 | -7 | -23 | -161 | -479 | -2,161 | -3,353 | -11,017 | -15,127 | -49,703 | -77,119 | -347,921 | -1,035,119 | -7,245,833 | -23,807,737 | -166,654,159 |
