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 152,751,205, 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 | 152,751,205 | |
| -1 | -152,751,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 152,751,205.
Example:
1 x 152,751,205 = 152,751,205
and
-1 x -152,751,205 = 152,751,205
Notice both answers equal 152,751,205
With that explanation out of the way, let's continue. Next, we take the number 152,751,205 and divide it by 2:
152,751,205 ÷ 2 = 76,375,602.5
If the quotient is a whole number, then 2 and 76,375,602.5 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 | 152,751,205 | |
| -1 | -152,751,205 |
Now, we try dividing 152,751,205 by 3:
152,751,205 ÷ 3 = 50,917,068.3333
If the quotient is a whole number, then 3 and 50,917,068.3333 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 | 152,751,205 | |
| -1 | -152,751,205 |
Let's try dividing by 4:
152,751,205 ÷ 4 = 38,187,801.25
If the quotient is a whole number, then 4 and 38,187,801.25 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 | 152,751,205 | |
| -1 | 152,751,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 317 | 1,585 | 5,389 | 5,669 | 26,945 | 28,345 | 96,373 | 481,865 | 1,797,073 | 8,985,365 | 30,550,241 | 152,751,205 |
| -1 | -5 | -17 | -85 | -317 | -1,585 | -5,389 | -5,669 | -26,945 | -28,345 | -96,373 | -481,865 | -1,797,073 | -8,985,365 | -30,550,241 | -152,751,205 |
