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 166,162,363, 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 | 166,162,363 | |
| -1 | -166,162,363 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,162,363.
Example:
1 x 166,162,363 = 166,162,363
and
-1 x -166,162,363 = 166,162,363
Notice both answers equal 166,162,363
With that explanation out of the way, let's continue. Next, we take the number 166,162,363 and divide it by 2:
166,162,363 ÷ 2 = 83,081,181.5
If the quotient is a whole number, then 2 and 83,081,181.5 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 | 166,162,363 | |
| -1 | -166,162,363 |
Now, we try dividing 166,162,363 by 3:
166,162,363 ÷ 3 = 55,387,454.3333
If the quotient is a whole number, then 3 and 55,387,454.3333 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 | 166,162,363 | |
| -1 | -166,162,363 |
Let's try dividing by 4:
166,162,363 ÷ 4 = 41,540,590.75
If the quotient is a whole number, then 4 and 41,540,590.75 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 | 166,162,363 | |
| -1 | 166,162,363 |
If you did it right, you will end up with this table:
| 1 | 43 | 151 | 157 | 163 | 6,493 | 6,751 | 7,009 | 23,707 | 24,613 | 25,591 | 1,019,401 | 1,058,359 | 1,100,413 | 3,864,241 | 166,162,363 |
| -1 | -43 | -151 | -157 | -163 | -6,493 | -6,751 | -7,009 | -23,707 | -24,613 | -25,591 | -1,019,401 | -1,058,359 | -1,100,413 | -3,864,241 | -166,162,363 |
