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 160,102,163, 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 | 160,102,163 | |
| -1 | -160,102,163 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 160,102,163.
Example:
1 x 160,102,163 = 160,102,163
and
-1 x -160,102,163 = 160,102,163
Notice both answers equal 160,102,163
With that explanation out of the way, let's continue. Next, we take the number 160,102,163 and divide it by 2:
160,102,163 ÷ 2 = 80,051,081.5
If the quotient is a whole number, then 2 and 80,051,081.5 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 | 160,102,163 | |
| -1 | -160,102,163 |
Now, we try dividing 160,102,163 by 3:
160,102,163 ÷ 3 = 53,367,387.6667
If the quotient is a whole number, then 3 and 53,367,387.6667 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 | 160,102,163 | |
| -1 | -160,102,163 |
Let's try dividing by 4:
160,102,163 ÷ 4 = 40,025,540.75
If the quotient is a whole number, then 4 and 40,025,540.75 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 | 160,102,163 | |
| -1 | 160,102,163 |
If you did it right, you will end up with this table:
| 1 | 13 | 47 | 157 | 611 | 1,669 | 2,041 | 7,379 | 21,697 | 78,443 | 95,927 | 262,033 | 1,019,759 | 3,406,429 | 12,315,551 | 160,102,163 |
| -1 | -13 | -47 | -157 | -611 | -1,669 | -2,041 | -7,379 | -21,697 | -78,443 | -95,927 | -262,033 | -1,019,759 | -3,406,429 | -12,315,551 | -160,102,163 |
