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 24,826,555, 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 | 24,826,555 | |
| -1 | -24,826,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,826,555.
Example:
1 x 24,826,555 = 24,826,555
and
-1 x -24,826,555 = 24,826,555
Notice both answers equal 24,826,555
With that explanation out of the way, let's continue. Next, we take the number 24,826,555 and divide it by 2:
24,826,555 ÷ 2 = 12,413,277.5
If the quotient is a whole number, then 2 and 12,413,277.5 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 | 24,826,555 | |
| -1 | -24,826,555 |
Now, we try dividing 24,826,555 by 3:
24,826,555 ÷ 3 = 8,275,518.3333
If the quotient is a whole number, then 3 and 8,275,518.3333 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 | 24,826,555 | |
| -1 | -24,826,555 |
Let's try dividing by 4:
24,826,555 ÷ 4 = 6,206,638.75
If the quotient is a whole number, then 4 and 6,206,638.75 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 | 24,826,555 | |
| -1 | 24,826,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 193 | 965 | 1,979 | 2,509 | 9,895 | 12,545 | 25,727 | 128,635 | 381,947 | 1,909,735 | 4,965,311 | 24,826,555 |
| -1 | -5 | -13 | -65 | -193 | -965 | -1,979 | -2,509 | -9,895 | -12,545 | -25,727 | -128,635 | -381,947 | -1,909,735 | -4,965,311 | -24,826,555 |
