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 28,652,617, 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 | 28,652,617 | |
| -1 | -28,652,617 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,652,617.
Example:
1 x 28,652,617 = 28,652,617
and
-1 x -28,652,617 = 28,652,617
Notice both answers equal 28,652,617
With that explanation out of the way, let's continue. Next, we take the number 28,652,617 and divide it by 2:
28,652,617 ÷ 2 = 14,326,308.5
If the quotient is a whole number, then 2 and 14,326,308.5 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 | 28,652,617 | |
| -1 | -28,652,617 |
Now, we try dividing 28,652,617 by 3:
28,652,617 ÷ 3 = 9,550,872.3333
If the quotient is a whole number, then 3 and 9,550,872.3333 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 | 28,652,617 | |
| -1 | -28,652,617 |
Let's try dividing by 4:
28,652,617 ÷ 4 = 7,163,154.25
If the quotient is a whole number, then 4 and 7,163,154.25 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 | 28,652,617 | |
| -1 | 28,652,617 |
If you did it right, you will end up with this table:
| 1 | 7 | 67 | 199 | 307 | 469 | 1,393 | 2,149 | 13,333 | 20,569 | 61,093 | 93,331 | 143,983 | 427,651 | 4,093,231 | 28,652,617 |
| -1 | -7 | -67 | -199 | -307 | -469 | -1,393 | -2,149 | -13,333 | -20,569 | -61,093 | -93,331 | -143,983 | -427,651 | -4,093,231 | -28,652,617 |
