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 152,013,125, 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 | 152,013,125 | |
| -1 | -152,013,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 152,013,125.
Example:
1 x 152,013,125 = 152,013,125
and
-1 x -152,013,125 = 152,013,125
Notice both answers equal 152,013,125
With that explanation out of the way, let's continue. Next, we take the number 152,013,125 and divide it by 2:
152,013,125 ÷ 2 = 76,006,562.5
If the quotient is a whole number, then 2 and 76,006,562.5 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 | 152,013,125 | |
| -1 | -152,013,125 |
Now, we try dividing 152,013,125 by 3:
152,013,125 ÷ 3 = 50,671,041.6667
If the quotient is a whole number, then 3 and 50,671,041.6667 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 | 152,013,125 | |
| -1 | -152,013,125 |
Let's try dividing by 4:
152,013,125 ÷ 4 = 38,003,281.25
If the quotient is a whole number, then 4 and 38,003,281.25 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 | 152,013,125 | |
| -1 | 152,013,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 125 | 275 | 625 | 1,375 | 6,875 | 22,111 | 110,555 | 243,221 | 552,775 | 1,216,105 | 2,763,875 | 6,080,525 | 13,819,375 | 30,402,625 | 152,013,125 |
| -1 | -5 | -11 | -25 | -55 | -125 | -275 | -625 | -1,375 | -6,875 | -22,111 | -110,555 | -243,221 | -552,775 | -1,216,105 | -2,763,875 | -6,080,525 | -13,819,375 | -30,402,625 | -152,013,125 |
