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 162,523,165, 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 | 162,523,165 | |
| -1 | -162,523,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 162,523,165.
Example:
1 x 162,523,165 = 162,523,165
and
-1 x -162,523,165 = 162,523,165
Notice both answers equal 162,523,165
With that explanation out of the way, let's continue. Next, we take the number 162,523,165 and divide it by 2:
162,523,165 ÷ 2 = 81,261,582.5
If the quotient is a whole number, then 2 and 81,261,582.5 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 | 162,523,165 | |
| -1 | -162,523,165 |
Now, we try dividing 162,523,165 by 3:
162,523,165 ÷ 3 = 54,174,388.3333
If the quotient is a whole number, then 3 and 54,174,388.3333 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 | 162,523,165 | |
| -1 | -162,523,165 |
Let's try dividing by 4:
162,523,165 ÷ 4 = 40,630,791.25
If the quotient is a whole number, then 4 and 40,630,791.25 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 | 162,523,165 | |
| -1 | 162,523,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 647 | 3,235 | 4,529 | 7,177 | 22,645 | 35,885 | 50,239 | 251,195 | 4,643,519 | 23,217,595 | 32,504,633 | 162,523,165 |
| -1 | -5 | -7 | -35 | -647 | -3,235 | -4,529 | -7,177 | -22,645 | -35,885 | -50,239 | -251,195 | -4,643,519 | -23,217,595 | -32,504,633 | -162,523,165 |
