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 25,657,375, 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 | 25,657,375 | |
| -1 | -25,657,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,657,375.
Example:
1 x 25,657,375 = 25,657,375
and
-1 x -25,657,375 = 25,657,375
Notice both answers equal 25,657,375
With that explanation out of the way, let's continue. Next, we take the number 25,657,375 and divide it by 2:
25,657,375 ÷ 2 = 12,828,687.5
If the quotient is a whole number, then 2 and 12,828,687.5 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 | 25,657,375 | |
| -1 | -25,657,375 |
Now, we try dividing 25,657,375 by 3:
25,657,375 ÷ 3 = 8,552,458.3333
If the quotient is a whole number, then 3 and 8,552,458.3333 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 | 25,657,375 | |
| -1 | -25,657,375 |
Let's try dividing by 4:
25,657,375 ÷ 4 = 6,414,343.75
If the quotient is a whole number, then 4 and 6,414,343.75 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 | 25,657,375 | |
| -1 | 25,657,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 83 | 125 | 415 | 2,075 | 2,473 | 10,375 | 12,365 | 61,825 | 205,259 | 309,125 | 1,026,295 | 5,131,475 | 25,657,375 |
| -1 | -5 | -25 | -83 | -125 | -415 | -2,075 | -2,473 | -10,375 | -12,365 | -61,825 | -205,259 | -309,125 | -1,026,295 | -5,131,475 | -25,657,375 |
