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 166,075, 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 | 166,075 | |
| -1 | -166,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,075.
Example:
1 x 166,075 = 166,075
and
-1 x -166,075 = 166,075
Notice both answers equal 166,075
With that explanation out of the way, let's continue. Next, we take the number 166,075 and divide it by 2:
166,075 ÷ 2 = 83,037.5
If the quotient is a whole number, then 2 and 83,037.5 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 | 166,075 | |
| -1 | -166,075 |
Now, we try dividing 166,075 by 3:
166,075 ÷ 3 = 55,358.3333
If the quotient is a whole number, then 3 and 55,358.3333 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 | 166,075 | |
| -1 | -166,075 |
Let's try dividing by 4:
166,075 ÷ 4 = 41,518.75
If the quotient is a whole number, then 4 and 41,518.75 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 | 166,075 | |
| -1 | 166,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 25 | 35 | 65 | 73 | 91 | 175 | 325 | 365 | 455 | 511 | 949 | 1,825 | 2,275 | 2,555 | 4,745 | 6,643 | 12,775 | 23,725 | 33,215 | 166,075 |
| -1 | -5 | -7 | -13 | -25 | -35 | -65 | -73 | -91 | -175 | -325 | -365 | -455 | -511 | -949 | -1,825 | -2,275 | -2,555 | -4,745 | -6,643 | -12,775 | -23,725 | -33,215 | -166,075 |
