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 25,941,475, 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 | 25,941,475 | |
| -1 | -25,941,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,941,475.
Example:
1 x 25,941,475 = 25,941,475
and
-1 x -25,941,475 = 25,941,475
Notice both answers equal 25,941,475
With that explanation out of the way, let's continue. Next, we take the number 25,941,475 and divide it by 2:
25,941,475 ÷ 2 = 12,970,737.5
If the quotient is a whole number, then 2 and 12,970,737.5 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 | 25,941,475 | |
| -1 | -25,941,475 |
Now, we try dividing 25,941,475 by 3:
25,941,475 ÷ 3 = 8,647,158.3333
If the quotient is a whole number, then 3 and 8,647,158.3333 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 | 25,941,475 | |
| -1 | -25,941,475 |
Let's try dividing by 4:
25,941,475 ÷ 4 = 6,485,368.75
If the quotient is a whole number, then 4 and 6,485,368.75 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 | 25,941,475 | |
| -1 | 25,941,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 271 | 547 | 1,355 | 1,897 | 2,735 | 3,829 | 6,775 | 9,485 | 13,675 | 19,145 | 47,425 | 95,725 | 148,237 | 741,185 | 1,037,659 | 3,705,925 | 5,188,295 | 25,941,475 |
| -1 | -5 | -7 | -25 | -35 | -175 | -271 | -547 | -1,355 | -1,897 | -2,735 | -3,829 | -6,775 | -9,485 | -13,675 | -19,145 | -47,425 | -95,725 | -148,237 | -741,185 | -1,037,659 | -3,705,925 | -5,188,295 | -25,941,475 |
