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 166,934,471, 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 | 166,934,471 | |
| -1 | -166,934,471 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,934,471.
Example:
1 x 166,934,471 = 166,934,471
and
-1 x -166,934,471 = 166,934,471
Notice both answers equal 166,934,471
With that explanation out of the way, let's continue. Next, we take the number 166,934,471 and divide it by 2:
166,934,471 ÷ 2 = 83,467,235.5
If the quotient is a whole number, then 2 and 83,467,235.5 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 | 166,934,471 | |
| -1 | -166,934,471 |
Now, we try dividing 166,934,471 by 3:
166,934,471 ÷ 3 = 55,644,823.6667
If the quotient is a whole number, then 3 and 55,644,823.6667 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 | 166,934,471 | |
| -1 | -166,934,471 |
Let's try dividing by 4:
166,934,471 ÷ 4 = 41,733,617.75
If the quotient is a whole number, then 4 and 41,733,617.75 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 | 166,934,471 | |
| -1 | 166,934,471 |
If you did it right, you will end up with this table:
| 1 | 11 | 43 | 53 | 473 | 583 | 2,279 | 6,659 | 25,069 | 73,249 | 286,337 | 352,927 | 3,149,707 | 3,882,197 | 15,175,861 | 166,934,471 |
| -1 | -11 | -43 | -53 | -473 | -583 | -2,279 | -6,659 | -25,069 | -73,249 | -286,337 | -352,927 | -3,149,707 | -3,882,197 | -15,175,861 | -166,934,471 |
