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 3,657,907, 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 | 3,657,907 | |
| -1 | -3,657,907 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,657,907.
Example:
1 x 3,657,907 = 3,657,907
and
-1 x -3,657,907 = 3,657,907
Notice both answers equal 3,657,907
With that explanation out of the way, let's continue. Next, we take the number 3,657,907 and divide it by 2:
3,657,907 ÷ 2 = 1,828,953.5
If the quotient is a whole number, then 2 and 1,828,953.5 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 | 3,657,907 | |
| -1 | -3,657,907 |
Now, we try dividing 3,657,907 by 3:
3,657,907 ÷ 3 = 1,219,302.3333
If the quotient is a whole number, then 3 and 1,219,302.3333 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 | 3,657,907 | |
| -1 | -3,657,907 |
Let's try dividing by 4:
3,657,907 ÷ 4 = 914,476.75
If the quotient is a whole number, then 4 and 914,476.75 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 | 3,657,907 | |
| -1 | 3,657,907 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 31 | 187 | 341 | 527 | 631 | 5,797 | 6,941 | 10,727 | 19,561 | 117,997 | 215,171 | 332,537 | 3,657,907 |
| -1 | -11 | -17 | -31 | -187 | -341 | -527 | -631 | -5,797 | -6,941 | -10,727 | -19,561 | -117,997 | -215,171 | -332,537 | -3,657,907 |
