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 166,574,729, 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 | 166,574,729 | |
| -1 | -166,574,729 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,574,729.
Example:
1 x 166,574,729 = 166,574,729
and
-1 x -166,574,729 = 166,574,729
Notice both answers equal 166,574,729
With that explanation out of the way, let's continue. Next, we take the number 166,574,729 and divide it by 2:
166,574,729 ÷ 2 = 83,287,364.5
If the quotient is a whole number, then 2 and 83,287,364.5 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 | 166,574,729 | |
| -1 | -166,574,729 |
Now, we try dividing 166,574,729 by 3:
166,574,729 ÷ 3 = 55,524,909.6667
If the quotient is a whole number, then 3 and 55,524,909.6667 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 | 166,574,729 | |
| -1 | -166,574,729 |
Let's try dividing by 4:
166,574,729 ÷ 4 = 41,643,682.25
If the quotient is a whole number, then 4 and 41,643,682.25 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 | 166,574,729 | |
| -1 | 166,574,729 |
If you did it right, you will end up with this table:
| 1 | 19 | 191 | 197 | 233 | 3,629 | 3,743 | 4,427 | 37,627 | 44,503 | 45,901 | 714,913 | 845,557 | 872,119 | 8,767,091 | 166,574,729 |
| -1 | -19 | -191 | -197 | -233 | -3,629 | -3,743 | -4,427 | -37,627 | -44,503 | -45,901 | -714,913 | -845,557 | -872,119 | -8,767,091 | -166,574,729 |
