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 4,206,917, 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 | 4,206,917 | |
| -1 | -4,206,917 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,206,917.
Example:
1 x 4,206,917 = 4,206,917
and
-1 x -4,206,917 = 4,206,917
Notice both answers equal 4,206,917
With that explanation out of the way, let's continue. Next, we take the number 4,206,917 and divide it by 2:
4,206,917 ÷ 2 = 2,103,458.5
If the quotient is a whole number, then 2 and 2,103,458.5 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 | 4,206,917 | |
| -1 | -4,206,917 |
Now, we try dividing 4,206,917 by 3:
4,206,917 ÷ 3 = 1,402,305.6667
If the quotient is a whole number, then 3 and 1,402,305.6667 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 | 4,206,917 | |
| -1 | -4,206,917 |
Let's try dividing by 4:
4,206,917 ÷ 4 = 1,051,729.25
If the quotient is a whole number, then 4 and 1,051,729.25 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 | 4,206,917 | |
| -1 | 4,206,917 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 31 | 73 | 143 | 169 | 341 | 403 | 803 | 949 | 1,859 | 2,263 | 4,433 | 5,239 | 10,439 | 12,337 | 24,893 | 29,419 | 57,629 | 135,707 | 323,609 | 382,447 | 4,206,917 |
| -1 | -11 | -13 | -31 | -73 | -143 | -169 | -341 | -403 | -803 | -949 | -1,859 | -2,263 | -4,433 | -5,239 | -10,439 | -12,337 | -24,893 | -29,419 | -57,629 | -135,707 | -323,609 | -382,447 | -4,206,917 |
