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 6,615,637, 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 | 6,615,637 | |
| -1 | -6,615,637 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,615,637.
Example:
1 x 6,615,637 = 6,615,637
and
-1 x -6,615,637 = 6,615,637
Notice both answers equal 6,615,637
With that explanation out of the way, let's continue. Next, we take the number 6,615,637 and divide it by 2:
6,615,637 ÷ 2 = 3,307,818.5
If the quotient is a whole number, then 2 and 3,307,818.5 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 | 6,615,637 | |
| -1 | -6,615,637 |
Now, we try dividing 6,615,637 by 3:
6,615,637 ÷ 3 = 2,205,212.3333
If the quotient is a whole number, then 3 and 2,205,212.3333 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 | 6,615,637 | |
| -1 | -6,615,637 |
Let's try dividing by 4:
6,615,637 ÷ 4 = 1,653,909.25
If the quotient is a whole number, then 4 and 1,653,909.25 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 | 6,615,637 | |
| -1 | 6,615,637 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 41 | 49 | 89 | 259 | 287 | 623 | 1,517 | 1,813 | 2,009 | 3,293 | 3,649 | 4,361 | 10,619 | 23,051 | 25,543 | 74,333 | 135,013 | 161,357 | 178,801 | 945,091 | 6,615,637 |
| -1 | -7 | -37 | -41 | -49 | -89 | -259 | -287 | -623 | -1,517 | -1,813 | -2,009 | -3,293 | -3,649 | -4,361 | -10,619 | -23,051 | -25,543 | -74,333 | -135,013 | -161,357 | -178,801 | -945,091 | -6,615,637 |
