A:
Positive:
1 x 254999997 x 364285767 x 380597469 x 54371
Negative:
-1 x -25499999-7 x -3642857-67 x -380597-469 x -54371
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 25,499,999, 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 | 25,499,999 | |
| -1 | -25,499,999 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,499,999.
Example:
1 x 25,499,999 = 25,499,999
and
-1 x -25,499,999 = 25,499,999
Notice both answers equal 25,499,999
With that explanation out of the way, let's continue. Next, we take the number 25,499,999 and divide it by 2:
25,499,999 ÷ 2 = 12,749,999.5
If the quotient is a whole number, then 2 and 12,749,999.5 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 | 25,499,999 | |
| -1 | -25,499,999 |
Now, we try dividing 25,499,999 by 3:
25,499,999 ÷ 3 = 8,499,999.6667
If the quotient is a whole number, then 3 and 8,499,999.6667 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 | 25,499,999 | |
| -1 | -25,499,999 |
Let's try dividing by 4:
25,499,999 ÷ 4 = 6,374,999.75
If the quotient is a whole number, then 4 and 6,374,999.75 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 | 25,499,999 | |
| -1 | 25,499,999 |
If you did it right, you will end up with this table:
| 1 | 7 | 67 | 469 | 54,371 | 380,597 | 3,642,857 | 25,499,999 |
| -1 | -7 | -67 | -469 | -54,371 | -380,597 | -3,642,857 | -25,499,999 |
