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 4,163,725, 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 | 4,163,725 | |
| -1 | -4,163,725 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,163,725.
Example:
1 x 4,163,725 = 4,163,725
and
-1 x -4,163,725 = 4,163,725
Notice both answers equal 4,163,725
With that explanation out of the way, let's continue. Next, we take the number 4,163,725 and divide it by 2:
4,163,725 ÷ 2 = 2,081,862.5
If the quotient is a whole number, then 2 and 2,081,862.5 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 | 4,163,725 | |
| -1 | -4,163,725 |
Now, we try dividing 4,163,725 by 3:
4,163,725 ÷ 3 = 1,387,908.3333
If the quotient is a whole number, then 3 and 1,387,908.3333 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 | 4,163,725 | |
| -1 | -4,163,725 |
Let's try dividing by 4:
4,163,725 ÷ 4 = 1,040,931.25
If the quotient is a whole number, then 4 and 1,040,931.25 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 | 4,163,725 | |
| -1 | 4,163,725 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 97 | 101 | 425 | 485 | 505 | 1,649 | 1,717 | 2,425 | 2,525 | 8,245 | 8,585 | 9,797 | 41,225 | 42,925 | 48,985 | 166,549 | 244,925 | 832,745 | 4,163,725 |
| -1 | -5 | -17 | -25 | -85 | -97 | -101 | -425 | -485 | -505 | -1,649 | -1,717 | -2,425 | -2,525 | -8,245 | -8,585 | -9,797 | -41,225 | -42,925 | -48,985 | -166,549 | -244,925 | -832,745 | -4,163,725 |
