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 4,185,775, 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 | 4,185,775 | |
| -1 | -4,185,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,185,775.
Example:
1 x 4,185,775 = 4,185,775
and
-1 x -4,185,775 = 4,185,775
Notice both answers equal 4,185,775
With that explanation out of the way, let's continue. Next, we take the number 4,185,775 and divide it by 2:
4,185,775 ÷ 2 = 2,092,887.5
If the quotient is a whole number, then 2 and 2,092,887.5 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 | 4,185,775 | |
| -1 | -4,185,775 |
Now, we try dividing 4,185,775 by 3:
4,185,775 ÷ 3 = 1,395,258.3333
If the quotient is a whole number, then 3 and 1,395,258.3333 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 | 4,185,775 | |
| -1 | -4,185,775 |
Let's try dividing by 4:
4,185,775 ÷ 4 = 1,046,443.75
If the quotient is a whole number, then 4 and 1,046,443.75 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 | 4,185,775 | |
| -1 | 4,185,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 31 | 55 | 155 | 275 | 341 | 491 | 775 | 1,705 | 2,455 | 5,401 | 8,525 | 12,275 | 15,221 | 27,005 | 76,105 | 135,025 | 167,431 | 380,525 | 837,155 | 4,185,775 |
| -1 | -5 | -11 | -25 | -31 | -55 | -155 | -275 | -341 | -491 | -775 | -1,705 | -2,455 | -5,401 | -8,525 | -12,275 | -15,221 | -27,005 | -76,105 | -135,025 | -167,431 | -380,525 | -837,155 | -4,185,775 |
