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 32,677,825, 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 | 32,677,825 | |
| -1 | -32,677,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,677,825.
Example:
1 x 32,677,825 = 32,677,825
and
-1 x -32,677,825 = 32,677,825
Notice both answers equal 32,677,825
With that explanation out of the way, let's continue. Next, we take the number 32,677,825 and divide it by 2:
32,677,825 ÷ 2 = 16,338,912.5
If the quotient is a whole number, then 2 and 16,338,912.5 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 | 32,677,825 | |
| -1 | -32,677,825 |
Now, we try dividing 32,677,825 by 3:
32,677,825 ÷ 3 = 10,892,608.3333
If the quotient is a whole number, then 3 and 10,892,608.3333 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 | 32,677,825 | |
| -1 | -32,677,825 |
Let's try dividing by 4:
32,677,825 ÷ 4 = 8,169,456.25
If the quotient is a whole number, then 4 and 8,169,456.25 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 | 32,677,825 | |
| -1 | 32,677,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 23 | 25 | 85 | 115 | 391 | 425 | 575 | 1,955 | 3,343 | 9,775 | 16,715 | 56,831 | 76,889 | 83,575 | 284,155 | 384,445 | 1,307,113 | 1,420,775 | 1,922,225 | 6,535,565 | 32,677,825 |
| -1 | -5 | -17 | -23 | -25 | -85 | -115 | -391 | -425 | -575 | -1,955 | -3,343 | -9,775 | -16,715 | -56,831 | -76,889 | -83,575 | -284,155 | -384,445 | -1,307,113 | -1,420,775 | -1,922,225 | -6,535,565 | -32,677,825 |
