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 176,211,119, 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 | 176,211,119 | |
| -1 | -176,211,119 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 176,211,119.
Example:
1 x 176,211,119 = 176,211,119
and
-1 x -176,211,119 = 176,211,119
Notice both answers equal 176,211,119
With that explanation out of the way, let's continue. Next, we take the number 176,211,119 and divide it by 2:
176,211,119 ÷ 2 = 88,105,559.5
If the quotient is a whole number, then 2 and 88,105,559.5 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 | 176,211,119 | |
| -1 | -176,211,119 |
Now, we try dividing 176,211,119 by 3:
176,211,119 ÷ 3 = 58,737,039.6667
If the quotient is a whole number, then 3 and 58,737,039.6667 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 | 176,211,119 | |
| -1 | -176,211,119 |
Let's try dividing by 4:
176,211,119 ÷ 4 = 44,052,779.75
If the quotient is a whole number, then 4 and 44,052,779.75 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 | 176,211,119 | |
| -1 | 176,211,119 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 43 | 161 | 301 | 989 | 6,923 | 25,453 | 178,171 | 585,419 | 1,094,479 | 4,097,933 | 7,661,353 | 25,173,017 | 176,211,119 |
| -1 | -7 | -23 | -43 | -161 | -301 | -989 | -6,923 | -25,453 | -178,171 | -585,419 | -1,094,479 | -4,097,933 | -7,661,353 | -25,173,017 | -176,211,119 |
