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 3,814,645, 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 | 3,814,645 | |
| -1 | -3,814,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,814,645.
Example:
1 x 3,814,645 = 3,814,645
and
-1 x -3,814,645 = 3,814,645
Notice both answers equal 3,814,645
With that explanation out of the way, let's continue. Next, we take the number 3,814,645 and divide it by 2:
3,814,645 ÷ 2 = 1,907,322.5
If the quotient is a whole number, then 2 and 1,907,322.5 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 | 3,814,645 | |
| -1 | -3,814,645 |
Now, we try dividing 3,814,645 by 3:
3,814,645 ÷ 3 = 1,271,548.3333
If the quotient is a whole number, then 3 and 1,271,548.3333 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 | 3,814,645 | |
| -1 | -3,814,645 |
Let's try dividing by 4:
3,814,645 ÷ 4 = 953,661.25
If the quotient is a whole number, then 4 and 953,661.25 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 | 3,814,645 | |
| -1 | 3,814,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 67 | 193 | 295 | 335 | 965 | 3,953 | 11,387 | 12,931 | 19,765 | 56,935 | 64,655 | 762,929 | 3,814,645 |
| -1 | -5 | -59 | -67 | -193 | -295 | -335 | -965 | -3,953 | -11,387 | -12,931 | -19,765 | -56,935 | -64,655 | -762,929 | -3,814,645 |
