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 176,162,245, 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 | 176,162,245 | |
| -1 | -176,162,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 176,162,245.
Example:
1 x 176,162,245 = 176,162,245
and
-1 x -176,162,245 = 176,162,245
Notice both answers equal 176,162,245
With that explanation out of the way, let's continue. Next, we take the number 176,162,245 and divide it by 2:
176,162,245 ÷ 2 = 88,081,122.5
If the quotient is a whole number, then 2 and 88,081,122.5 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 | 176,162,245 | |
| -1 | -176,162,245 |
Now, we try dividing 176,162,245 by 3:
176,162,245 ÷ 3 = 58,720,748.3333
If the quotient is a whole number, then 3 and 58,720,748.3333 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 | 176,162,245 | |
| -1 | -176,162,245 |
Let's try dividing by 4:
176,162,245 ÷ 4 = 44,040,561.25
If the quotient is a whole number, then 4 and 44,040,561.25 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 | 176,162,245 | |
| -1 | 176,162,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 296,071 | 1,480,355 | 2,072,497 | 5,033,207 | 10,362,485 | 25,166,035 | 35,232,449 | 176,162,245 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -296,071 | -1,480,355 | -2,072,497 | -5,033,207 | -10,362,485 | -25,166,035 | -35,232,449 | -176,162,245 |
