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 25,712,795, 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 | 25,712,795 | |
| -1 | -25,712,795 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,712,795.
Example:
1 x 25,712,795 = 25,712,795
and
-1 x -25,712,795 = 25,712,795
Notice both answers equal 25,712,795
With that explanation out of the way, let's continue. Next, we take the number 25,712,795 and divide it by 2:
25,712,795 ÷ 2 = 12,856,397.5
If the quotient is a whole number, then 2 and 12,856,397.5 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 | 25,712,795 | |
| -1 | -25,712,795 |
Now, we try dividing 25,712,795 by 3:
25,712,795 ÷ 3 = 8,570,931.6667
If the quotient is a whole number, then 3 and 8,570,931.6667 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 | 25,712,795 | |
| -1 | -25,712,795 |
Let's try dividing by 4:
25,712,795 ÷ 4 = 6,428,198.75
If the quotient is a whole number, then 4 and 6,428,198.75 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 | 25,712,795 | |
| -1 | 25,712,795 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 31 | 95 | 155 | 589 | 2,945 | 8,731 | 43,655 | 165,889 | 270,661 | 829,445 | 1,353,305 | 5,142,559 | 25,712,795 |
| -1 | -5 | -19 | -31 | -95 | -155 | -589 | -2,945 | -8,731 | -43,655 | -165,889 | -270,661 | -829,445 | -1,353,305 | -5,142,559 | -25,712,795 |
