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 32,118,865, 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 | 32,118,865 | |
| -1 | -32,118,865 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,118,865.
Example:
1 x 32,118,865 = 32,118,865
and
-1 x -32,118,865 = 32,118,865
Notice both answers equal 32,118,865
With that explanation out of the way, let's continue. Next, we take the number 32,118,865 and divide it by 2:
32,118,865 ÷ 2 = 16,059,432.5
If the quotient is a whole number, then 2 and 16,059,432.5 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 | 32,118,865 | |
| -1 | -32,118,865 |
Now, we try dividing 32,118,865 by 3:
32,118,865 ÷ 3 = 10,706,288.3333
If the quotient is a whole number, then 3 and 10,706,288.3333 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 | 32,118,865 | |
| -1 | -32,118,865 |
Let's try dividing by 4:
32,118,865 ÷ 4 = 8,029,716.25
If the quotient is a whole number, then 4 and 8,029,716.25 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 | 32,118,865 | |
| -1 | 32,118,865 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 179 | 895 | 2,111 | 3,043 | 10,555 | 15,215 | 35,887 | 179,435 | 377,869 | 1,889,345 | 6,423,773 | 32,118,865 |
| -1 | -5 | -17 | -85 | -179 | -895 | -2,111 | -3,043 | -10,555 | -15,215 | -35,887 | -179,435 | -377,869 | -1,889,345 | -6,423,773 | -32,118,865 |
