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 32,152,015, 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 | 32,152,015 | |
| -1 | -32,152,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,152,015.
Example:
1 x 32,152,015 = 32,152,015
and
-1 x -32,152,015 = 32,152,015
Notice both answers equal 32,152,015
With that explanation out of the way, let's continue. Next, we take the number 32,152,015 and divide it by 2:
32,152,015 ÷ 2 = 16,076,007.5
If the quotient is a whole number, then 2 and 16,076,007.5 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 | 32,152,015 | |
| -1 | -32,152,015 |
Now, we try dividing 32,152,015 by 3:
32,152,015 ÷ 3 = 10,717,338.3333
If the quotient is a whole number, then 3 and 10,717,338.3333 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 | 32,152,015 | |
| -1 | -32,152,015 |
Let's try dividing by 4:
32,152,015 ÷ 4 = 8,038,003.75
If the quotient is a whole number, then 4 and 8,038,003.75 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 | 32,152,015 | |
| -1 | 32,152,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 54,037 | 270,185 | 378,259 | 918,629 | 1,891,295 | 4,593,145 | 6,430,403 | 32,152,015 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -54,037 | -270,185 | -378,259 | -918,629 | -1,891,295 | -4,593,145 | -6,430,403 | -32,152,015 |
