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 166,425,181, 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 | 166,425,181 | |
| -1 | -166,425,181 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,425,181.
Example:
1 x 166,425,181 = 166,425,181
and
-1 x -166,425,181 = 166,425,181
Notice both answers equal 166,425,181
With that explanation out of the way, let's continue. Next, we take the number 166,425,181 and divide it by 2:
166,425,181 ÷ 2 = 83,212,590.5
If the quotient is a whole number, then 2 and 83,212,590.5 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 | 166,425,181 | |
| -1 | -166,425,181 |
Now, we try dividing 166,425,181 by 3:
166,425,181 ÷ 3 = 55,475,060.3333
If the quotient is a whole number, then 3 and 55,475,060.3333 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 | 166,425,181 | |
| -1 | -166,425,181 |
Let's try dividing by 4:
166,425,181 ÷ 4 = 41,606,295.25
If the quotient is a whole number, then 4 and 41,606,295.25 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 | 166,425,181 | |
| -1 | 166,425,181 |
If you did it right, you will end up with this table:
| 1 | 13 | 73 | 157 | 949 | 1,117 | 2,041 | 11,461 | 14,521 | 81,541 | 148,993 | 175,369 | 1,060,033 | 2,279,797 | 12,801,937 | 166,425,181 |
| -1 | -13 | -73 | -157 | -949 | -1,117 | -2,041 | -11,461 | -14,521 | -81,541 | -148,993 | -175,369 | -1,060,033 | -2,279,797 | -12,801,937 | -166,425,181 |
