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 4,168,645, 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 | 4,168,645 | |
| -1 | -4,168,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,168,645.
Example:
1 x 4,168,645 = 4,168,645
and
-1 x -4,168,645 = 4,168,645
Notice both answers equal 4,168,645
With that explanation out of the way, let's continue. Next, we take the number 4,168,645 and divide it by 2:
4,168,645 ÷ 2 = 2,084,322.5
If the quotient is a whole number, then 2 and 2,084,322.5 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 | 4,168,645 | |
| -1 | -4,168,645 |
Now, we try dividing 4,168,645 by 3:
4,168,645 ÷ 3 = 1,389,548.3333
If the quotient is a whole number, then 3 and 1,389,548.3333 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 | 4,168,645 | |
| -1 | -4,168,645 |
Let's try dividing by 4:
4,168,645 ÷ 4 = 1,042,161.25
If the quotient is a whole number, then 4 and 1,042,161.25 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 | 4,168,645 | |
| -1 | 4,168,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 59 | 65 | 295 | 767 | 1,087 | 3,835 | 5,435 | 14,131 | 64,133 | 70,655 | 320,665 | 833,729 | 4,168,645 |
| -1 | -5 | -13 | -59 | -65 | -295 | -767 | -1,087 | -3,835 | -5,435 | -14,131 | -64,133 | -70,655 | -320,665 | -833,729 | -4,168,645 |
