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 24,470,255, 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 | 24,470,255 | |
| -1 | -24,470,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,470,255.
Example:
1 x 24,470,255 = 24,470,255
and
-1 x -24,470,255 = 24,470,255
Notice both answers equal 24,470,255
With that explanation out of the way, let's continue. Next, we take the number 24,470,255 and divide it by 2:
24,470,255 ÷ 2 = 12,235,127.5
If the quotient is a whole number, then 2 and 12,235,127.5 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 | 24,470,255 | |
| -1 | -24,470,255 |
Now, we try dividing 24,470,255 by 3:
24,470,255 ÷ 3 = 8,156,751.6667
If the quotient is a whole number, then 3 and 8,156,751.6667 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 | 24,470,255 | |
| -1 | -24,470,255 |
Let's try dividing by 4:
24,470,255 ÷ 4 = 6,117,563.75
If the quotient is a whole number, then 4 and 6,117,563.75 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 | 24,470,255 | |
| -1 | 24,470,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 137 | 139 | 257 | 685 | 695 | 1,285 | 19,043 | 35,209 | 35,723 | 95,215 | 176,045 | 178,615 | 4,894,051 | 24,470,255 |
| -1 | -5 | -137 | -139 | -257 | -685 | -695 | -1,285 | -19,043 | -35,209 | -35,723 | -95,215 | -176,045 | -178,615 | -4,894,051 | -24,470,255 |
