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 6,241,385, 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 | 6,241,385 | |
| -1 | -6,241,385 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,241,385.
Example:
1 x 6,241,385 = 6,241,385
and
-1 x -6,241,385 = 6,241,385
Notice both answers equal 6,241,385
With that explanation out of the way, let's continue. Next, we take the number 6,241,385 and divide it by 2:
6,241,385 ÷ 2 = 3,120,692.5
If the quotient is a whole number, then 2 and 3,120,692.5 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 | 6,241,385 | |
| -1 | -6,241,385 |
Now, we try dividing 6,241,385 by 3:
6,241,385 ÷ 3 = 2,080,461.6667
If the quotient is a whole number, then 3 and 2,080,461.6667 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 | 6,241,385 | |
| -1 | -6,241,385 |
Let's try dividing by 4:
6,241,385 ÷ 4 = 1,560,346.25
If the quotient is a whole number, then 4 and 1,560,346.25 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 | 6,241,385 | |
| -1 | 6,241,385 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 67 | 155 | 335 | 601 | 2,077 | 3,005 | 10,385 | 18,631 | 40,267 | 93,155 | 201,335 | 1,248,277 | 6,241,385 |
| -1 | -5 | -31 | -67 | -155 | -335 | -601 | -2,077 | -3,005 | -10,385 | -18,631 | -40,267 | -93,155 | -201,335 | -1,248,277 | -6,241,385 |
