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 28,662,355, 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 | 28,662,355 | |
| -1 | -28,662,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,662,355.
Example:
1 x 28,662,355 = 28,662,355
and
-1 x -28,662,355 = 28,662,355
Notice both answers equal 28,662,355
With that explanation out of the way, let's continue. Next, we take the number 28,662,355 and divide it by 2:
28,662,355 ÷ 2 = 14,331,177.5
If the quotient is a whole number, then 2 and 14,331,177.5 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 | 28,662,355 | |
| -1 | -28,662,355 |
Now, we try dividing 28,662,355 by 3:
28,662,355 ÷ 3 = 9,554,118.3333
If the quotient is a whole number, then 3 and 9,554,118.3333 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 | 28,662,355 | |
| -1 | -28,662,355 |
Let's try dividing by 4:
28,662,355 ÷ 4 = 7,165,588.75
If the quotient is a whole number, then 4 and 7,165,588.75 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 | 28,662,355 | |
| -1 | 28,662,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 73 | 95 | 365 | 1,387 | 4,133 | 6,935 | 20,665 | 78,527 | 301,709 | 392,635 | 1,508,545 | 5,732,471 | 28,662,355 |
| -1 | -5 | -19 | -73 | -95 | -365 | -1,387 | -4,133 | -6,935 | -20,665 | -78,527 | -301,709 | -392,635 | -1,508,545 | -5,732,471 | -28,662,355 |
