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 4,182,805, 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 | 4,182,805 | |
| -1 | -4,182,805 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,182,805.
Example:
1 x 4,182,805 = 4,182,805
and
-1 x -4,182,805 = 4,182,805
Notice both answers equal 4,182,805
With that explanation out of the way, let's continue. Next, we take the number 4,182,805 and divide it by 2:
4,182,805 ÷ 2 = 2,091,402.5
If the quotient is a whole number, then 2 and 2,091,402.5 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 | 4,182,805 | |
| -1 | -4,182,805 |
Now, we try dividing 4,182,805 by 3:
4,182,805 ÷ 3 = 1,394,268.3333
If the quotient is a whole number, then 3 and 1,394,268.3333 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 | 4,182,805 | |
| -1 | -4,182,805 |
Let's try dividing by 4:
4,182,805 ÷ 4 = 1,045,701.25
If the quotient is a whole number, then 4 and 1,045,701.25 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 | 4,182,805 | |
| -1 | 4,182,805 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 59 | 295 | 649 | 1,289 | 3,245 | 6,445 | 14,179 | 70,895 | 76,051 | 380,255 | 836,561 | 4,182,805 |
| -1 | -5 | -11 | -55 | -59 | -295 | -649 | -1,289 | -3,245 | -6,445 | -14,179 | -70,895 | -76,051 | -380,255 | -836,561 | -4,182,805 |
