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 162,656,215, 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 | 162,656,215 | |
| -1 | -162,656,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 162,656,215.
Example:
1 x 162,656,215 = 162,656,215
and
-1 x -162,656,215 = 162,656,215
Notice both answers equal 162,656,215
With that explanation out of the way, let's continue. Next, we take the number 162,656,215 and divide it by 2:
162,656,215 ÷ 2 = 81,328,107.5
If the quotient is a whole number, then 2 and 81,328,107.5 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 | 162,656,215 | |
| -1 | -162,656,215 |
Now, we try dividing 162,656,215 by 3:
162,656,215 ÷ 3 = 54,218,738.3333
If the quotient is a whole number, then 3 and 54,218,738.3333 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 | 162,656,215 | |
| -1 | -162,656,215 |
Let's try dividing by 4:
162,656,215 ÷ 4 = 40,664,053.75
If the quotient is a whole number, then 4 and 40,664,053.75 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 | 162,656,215 | |
| -1 | 162,656,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 59 | 145 | 295 | 1,711 | 8,555 | 19,013 | 95,065 | 551,377 | 1,121,767 | 2,756,885 | 5,608,835 | 32,531,243 | 162,656,215 |
| -1 | -5 | -29 | -59 | -145 | -295 | -1,711 | -8,555 | -19,013 | -95,065 | -551,377 | -1,121,767 | -2,756,885 | -5,608,835 | -32,531,243 | -162,656,215 |
