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 4,057,025, 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 | 4,057,025 | |
| -1 | -4,057,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,057,025.
Example:
1 x 4,057,025 = 4,057,025
and
-1 x -4,057,025 = 4,057,025
Notice both answers equal 4,057,025
With that explanation out of the way, let's continue. Next, we take the number 4,057,025 and divide it by 2:
4,057,025 ÷ 2 = 2,028,512.5
If the quotient is a whole number, then 2 and 2,028,512.5 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 | 4,057,025 | |
| -1 | -4,057,025 |
Now, we try dividing 4,057,025 by 3:
4,057,025 ÷ 3 = 1,352,341.6667
If the quotient is a whole number, then 3 and 1,352,341.6667 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 | 4,057,025 | |
| -1 | -4,057,025 |
Let's try dividing by 4:
4,057,025 ÷ 4 = 1,014,256.25
If the quotient is a whole number, then 4 and 1,014,256.25 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 | 4,057,025 | |
| -1 | 4,057,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 97 | 175 | 239 | 485 | 679 | 1,195 | 1,673 | 2,425 | 3,395 | 5,975 | 8,365 | 16,975 | 23,183 | 41,825 | 115,915 | 162,281 | 579,575 | 811,405 | 4,057,025 |
| -1 | -5 | -7 | -25 | -35 | -97 | -175 | -239 | -485 | -679 | -1,195 | -1,673 | -2,425 | -3,395 | -5,975 | -8,365 | -16,975 | -23,183 | -41,825 | -115,915 | -162,281 | -579,575 | -811,405 | -4,057,025 |
