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 24,612,419, 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 | 24,612,419 | |
| -1 | -24,612,419 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,612,419.
Example:
1 x 24,612,419 = 24,612,419
and
-1 x -24,612,419 = 24,612,419
Notice both answers equal 24,612,419
With that explanation out of the way, let's continue. Next, we take the number 24,612,419 and divide it by 2:
24,612,419 ÷ 2 = 12,306,209.5
If the quotient is a whole number, then 2 and 12,306,209.5 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 | 24,612,419 | |
| -1 | -24,612,419 |
Now, we try dividing 24,612,419 by 3:
24,612,419 ÷ 3 = 8,204,139.6667
If the quotient is a whole number, then 3 and 8,204,139.6667 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 | 24,612,419 | |
| -1 | -24,612,419 |
Let's try dividing by 4:
24,612,419 ÷ 4 = 6,153,104.75
If the quotient is a whole number, then 4 and 6,153,104.75 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 | 24,612,419 | |
| -1 | 24,612,419 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 157 | 389 | 403 | 2,041 | 4,867 | 5,057 | 12,059 | 61,073 | 63,271 | 156,767 | 793,949 | 1,893,263 | 24,612,419 |
| -1 | -13 | -31 | -157 | -389 | -403 | -2,041 | -4,867 | -5,057 | -12,059 | -61,073 | -63,271 | -156,767 | -793,949 | -1,893,263 | -24,612,419 |
