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 166,252,445, 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 | 166,252,445 | |
| -1 | -166,252,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,252,445.
Example:
1 x 166,252,445 = 166,252,445
and
-1 x -166,252,445 = 166,252,445
Notice both answers equal 166,252,445
With that explanation out of the way, let's continue. Next, we take the number 166,252,445 and divide it by 2:
166,252,445 ÷ 2 = 83,126,222.5
If the quotient is a whole number, then 2 and 83,126,222.5 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 | 166,252,445 | |
| -1 | -166,252,445 |
Now, we try dividing 166,252,445 by 3:
166,252,445 ÷ 3 = 55,417,481.6667
If the quotient is a whole number, then 3 and 55,417,481.6667 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 | 166,252,445 | |
| -1 | -166,252,445 |
Let's try dividing by 4:
166,252,445 ÷ 4 = 41,563,111.25
If the quotient is a whole number, then 4 and 41,563,111.25 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 | 166,252,445 | |
| -1 | 166,252,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 89 | 445 | 547 | 683 | 2,735 | 3,415 | 48,683 | 60,787 | 243,415 | 303,935 | 373,601 | 1,868,005 | 33,250,489 | 166,252,445 |
| -1 | -5 | -89 | -445 | -547 | -683 | -2,735 | -3,415 | -48,683 | -60,787 | -243,415 | -303,935 | -373,601 | -1,868,005 | -33,250,489 | -166,252,445 |
