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 25,433,401, 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 | 25,433,401 | |
| -1 | -25,433,401 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,433,401.
Example:
1 x 25,433,401 = 25,433,401
and
-1 x -25,433,401 = 25,433,401
Notice both answers equal 25,433,401
With that explanation out of the way, let's continue. Next, we take the number 25,433,401 and divide it by 2:
25,433,401 ÷ 2 = 12,716,700.5
If the quotient is a whole number, then 2 and 12,716,700.5 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 | 25,433,401 | |
| -1 | -25,433,401 |
Now, we try dividing 25,433,401 by 3:
25,433,401 ÷ 3 = 8,477,800.3333
If the quotient is a whole number, then 3 and 8,477,800.3333 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 | 25,433,401 | |
| -1 | -25,433,401 |
Let's try dividing by 4:
25,433,401 ÷ 4 = 6,358,350.25
If the quotient is a whole number, then 4 and 6,358,350.25 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 | 25,433,401 | |
| -1 | 25,433,401 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 61 | 67 | 127 | 427 | 469 | 889 | 2,989 | 3,283 | 4,087 | 6,223 | 7,747 | 8,509 | 28,609 | 54,229 | 59,563 | 200,263 | 379,603 | 416,941 | 519,049 | 3,633,343 | 25,433,401 |
| -1 | -7 | -49 | -61 | -67 | -127 | -427 | -469 | -889 | -2,989 | -3,283 | -4,087 | -6,223 | -7,747 | -8,509 | -28,609 | -54,229 | -59,563 | -200,263 | -379,603 | -416,941 | -519,049 | -3,633,343 | -25,433,401 |
