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 152,035,331, 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 | 152,035,331 | |
| -1 | -152,035,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 152,035,331.
Example:
1 x 152,035,331 = 152,035,331
and
-1 x -152,035,331 = 152,035,331
Notice both answers equal 152,035,331
With that explanation out of the way, let's continue. Next, we take the number 152,035,331 and divide it by 2:
152,035,331 ÷ 2 = 76,017,665.5
If the quotient is a whole number, then 2 and 76,017,665.5 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 | 152,035,331 | |
| -1 | -152,035,331 |
Now, we try dividing 152,035,331 by 3:
152,035,331 ÷ 3 = 50,678,443.6667
If the quotient is a whole number, then 3 and 50,678,443.6667 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 | 152,035,331 | |
| -1 | -152,035,331 |
Let's try dividing by 4:
152,035,331 ÷ 4 = 38,008,832.75
If the quotient is a whole number, then 4 and 38,008,832.75 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 | 152,035,331 | |
| -1 | 152,035,331 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 259 | 281 | 1,967 | 2,089 | 10,397 | 14,623 | 72,779 | 77,293 | 541,051 | 587,009 | 4,109,063 | 21,719,333 | 152,035,331 |
| -1 | -7 | -37 | -259 | -281 | -1,967 | -2,089 | -10,397 | -14,623 | -72,779 | -77,293 | -541,051 | -587,009 | -4,109,063 | -21,719,333 | -152,035,331 |
