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 152,255,155, 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 | 152,255,155 | |
| -1 | -152,255,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 152,255,155.
Example:
1 x 152,255,155 = 152,255,155
and
-1 x -152,255,155 = 152,255,155
Notice both answers equal 152,255,155
With that explanation out of the way, let's continue. Next, we take the number 152,255,155 and divide it by 2:
152,255,155 ÷ 2 = 76,127,577.5
If the quotient is a whole number, then 2 and 76,127,577.5 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 | 152,255,155 | |
| -1 | -152,255,155 |
Now, we try dividing 152,255,155 by 3:
152,255,155 ÷ 3 = 50,751,718.3333
If the quotient is a whole number, then 3 and 50,751,718.3333 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 | 152,255,155 | |
| -1 | -152,255,155 |
Let's try dividing by 4:
152,255,155 ÷ 4 = 38,063,788.75
If the quotient is a whole number, then 4 and 38,063,788.75 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 | 152,255,155 | |
| -1 | 152,255,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 67 | 335 | 871 | 4,355 | 34,961 | 174,805 | 454,493 | 2,272,465 | 2,342,387 | 11,711,935 | 30,451,031 | 152,255,155 |
| -1 | -5 | -13 | -65 | -67 | -335 | -871 | -4,355 | -34,961 | -174,805 | -454,493 | -2,272,465 | -2,342,387 | -11,711,935 | -30,451,031 | -152,255,155 |
