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 6,620,537, 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 | 6,620,537 | |
| -1 | -6,620,537 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,620,537.
Example:
1 x 6,620,537 = 6,620,537
and
-1 x -6,620,537 = 6,620,537
Notice both answers equal 6,620,537
With that explanation out of the way, let's continue. Next, we take the number 6,620,537 and divide it by 2:
6,620,537 ÷ 2 = 3,310,268.5
If the quotient is a whole number, then 2 and 3,310,268.5 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 | 6,620,537 | |
| -1 | -6,620,537 |
Now, we try dividing 6,620,537 by 3:
6,620,537 ÷ 3 = 2,206,845.6667
If the quotient is a whole number, then 3 and 2,206,845.6667 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 | 6,620,537 | |
| -1 | -6,620,537 |
Let's try dividing by 4:
6,620,537 ÷ 4 = 1,655,134.25
If the quotient is a whole number, then 4 and 1,655,134.25 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 | 6,620,537 | |
| -1 | 6,620,537 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 71 | 77 | 173 | 497 | 539 | 781 | 1,211 | 1,903 | 3,479 | 5,467 | 8,477 | 12,283 | 13,321 | 38,269 | 85,981 | 93,247 | 135,113 | 601,867 | 945,791 | 6,620,537 |
| -1 | -7 | -11 | -49 | -71 | -77 | -173 | -497 | -539 | -781 | -1,211 | -1,903 | -3,479 | -5,467 | -8,477 | -12,283 | -13,321 | -38,269 | -85,981 | -93,247 | -135,113 | -601,867 | -945,791 | -6,620,537 |
