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 152,111,413, 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 | 152,111,413 | |
| -1 | -152,111,413 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 152,111,413.
Example:
1 x 152,111,413 = 152,111,413
and
-1 x -152,111,413 = 152,111,413
Notice both answers equal 152,111,413
With that explanation out of the way, let's continue. Next, we take the number 152,111,413 and divide it by 2:
152,111,413 ÷ 2 = 76,055,706.5
If the quotient is a whole number, then 2 and 76,055,706.5 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 | 152,111,413 | |
| -1 | -152,111,413 |
Now, we try dividing 152,111,413 by 3:
152,111,413 ÷ 3 = 50,703,804.3333
If the quotient is a whole number, then 3 and 50,703,804.3333 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 | 152,111,413 | |
| -1 | -152,111,413 |
Let's try dividing by 4:
152,111,413 ÷ 4 = 38,027,853.25
If the quotient is a whole number, then 4 and 38,027,853.25 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 | 152,111,413 | |
| -1 | 152,111,413 |
If you did it right, you will end up with this table:
| 1 | 89 | 1,213 | 1,409 | 107,957 | 125,401 | 1,709,117 | 152,111,413 |
| -1 | -89 | -1,213 | -1,409 | -107,957 | -125,401 | -1,709,117 | -152,111,413 |
