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 4,171,825, 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 | 4,171,825 | |
| -1 | -4,171,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,171,825.
Example:
1 x 4,171,825 = 4,171,825
and
-1 x -4,171,825 = 4,171,825
Notice both answers equal 4,171,825
With that explanation out of the way, let's continue. Next, we take the number 4,171,825 and divide it by 2:
4,171,825 ÷ 2 = 2,085,912.5
If the quotient is a whole number, then 2 and 2,085,912.5 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 | 4,171,825 | |
| -1 | -4,171,825 |
Now, we try dividing 4,171,825 by 3:
4,171,825 ÷ 3 = 1,390,608.3333
If the quotient is a whole number, then 3 and 1,390,608.3333 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 | 4,171,825 | |
| -1 | -4,171,825 |
Let's try dividing by 4:
4,171,825 ÷ 4 = 1,042,956.25
If the quotient is a whole number, then 4 and 1,042,956.25 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 | 4,171,825 | |
| -1 | 4,171,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 31 | 35 | 155 | 175 | 217 | 769 | 775 | 1,085 | 3,845 | 5,383 | 5,425 | 19,225 | 23,839 | 26,915 | 119,195 | 134,575 | 166,873 | 595,975 | 834,365 | 4,171,825 |
| -1 | -5 | -7 | -25 | -31 | -35 | -155 | -175 | -217 | -769 | -775 | -1,085 | -3,845 | -5,383 | -5,425 | -19,225 | -23,839 | -26,915 | -119,195 | -134,575 | -166,873 | -595,975 | -834,365 | -4,171,825 |
