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 166,801,355, 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 | 166,801,355 | |
| -1 | -166,801,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,801,355.
Example:
1 x 166,801,355 = 166,801,355
and
-1 x -166,801,355 = 166,801,355
Notice both answers equal 166,801,355
With that explanation out of the way, let's continue. Next, we take the number 166,801,355 and divide it by 2:
166,801,355 ÷ 2 = 83,400,677.5
If the quotient is a whole number, then 2 and 83,400,677.5 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 | 166,801,355 | |
| -1 | -166,801,355 |
Now, we try dividing 166,801,355 by 3:
166,801,355 ÷ 3 = 55,600,451.6667
If the quotient is a whole number, then 3 and 55,600,451.6667 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 | 166,801,355 | |
| -1 | -166,801,355 |
Let's try dividing by 4:
166,801,355 ÷ 4 = 41,700,338.75
If the quotient is a whole number, then 4 and 41,700,338.75 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 | 166,801,355 | |
| -1 | 166,801,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 47 | 235 | 329 | 1,645 | 101,399 | 506,995 | 709,793 | 3,548,965 | 4,765,753 | 23,828,765 | 33,360,271 | 166,801,355 |
| -1 | -5 | -7 | -35 | -47 | -235 | -329 | -1,645 | -101,399 | -506,995 | -709,793 | -3,548,965 | -4,765,753 | -23,828,765 | -33,360,271 | -166,801,355 |
