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 3,683,849, 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 | 3,683,849 | |
| -1 | -3,683,849 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,683,849.
Example:
1 x 3,683,849 = 3,683,849
and
-1 x -3,683,849 = 3,683,849
Notice both answers equal 3,683,849
With that explanation out of the way, let's continue. Next, we take the number 3,683,849 and divide it by 2:
3,683,849 ÷ 2 = 1,841,924.5
If the quotient is a whole number, then 2 and 1,841,924.5 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 | 3,683,849 | |
| -1 | -3,683,849 |
Now, we try dividing 3,683,849 by 3:
3,683,849 ÷ 3 = 1,227,949.6667
If the quotient is a whole number, then 3 and 1,227,949.6667 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 | 3,683,849 | |
| -1 | -3,683,849 |
Let's try dividing by 4:
3,683,849 ÷ 4 = 920,962.25
If the quotient is a whole number, then 4 and 920,962.25 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 | 3,683,849 | |
| -1 | 3,683,849 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 79 | 211 | 221 | 1,027 | 1,343 | 2,743 | 3,587 | 16,669 | 17,459 | 46,631 | 216,697 | 283,373 | 3,683,849 |
| -1 | -13 | -17 | -79 | -211 | -221 | -1,027 | -1,343 | -2,743 | -3,587 | -16,669 | -17,459 | -46,631 | -216,697 | -283,373 | -3,683,849 |
