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 3,837,205, 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 | 3,837,205 | |
| -1 | -3,837,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,837,205.
Example:
1 x 3,837,205 = 3,837,205
and
-1 x -3,837,205 = 3,837,205
Notice both answers equal 3,837,205
With that explanation out of the way, let's continue. Next, we take the number 3,837,205 and divide it by 2:
3,837,205 ÷ 2 = 1,918,602.5
If the quotient is a whole number, then 2 and 1,918,602.5 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 | 3,837,205 | |
| -1 | -3,837,205 |
Now, we try dividing 3,837,205 by 3:
3,837,205 ÷ 3 = 1,279,068.3333
If the quotient is a whole number, then 3 and 1,279,068.3333 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 | 3,837,205 | |
| -1 | -3,837,205 |
Let's try dividing by 4:
3,837,205 ÷ 4 = 959,301.25
If the quotient is a whole number, then 4 and 959,301.25 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 | 3,837,205 | |
| -1 | 3,837,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 61 | 115 | 305 | 547 | 1,403 | 2,735 | 7,015 | 12,581 | 33,367 | 62,905 | 166,835 | 767,441 | 3,837,205 |
| -1 | -5 | -23 | -61 | -115 | -305 | -547 | -1,403 | -2,735 | -7,015 | -12,581 | -33,367 | -62,905 | -166,835 | -767,441 | -3,837,205 |
