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 6,780,865, 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 | 6,780,865 | |
| -1 | -6,780,865 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,780,865.
Example:
1 x 6,780,865 = 6,780,865
and
-1 x -6,780,865 = 6,780,865
Notice both answers equal 6,780,865
With that explanation out of the way, let's continue. Next, we take the number 6,780,865 and divide it by 2:
6,780,865 ÷ 2 = 3,390,432.5
If the quotient is a whole number, then 2 and 3,390,432.5 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 | 6,780,865 | |
| -1 | -6,780,865 |
Now, we try dividing 6,780,865 by 3:
6,780,865 ÷ 3 = 2,260,288.3333
If the quotient is a whole number, then 3 and 2,260,288.3333 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 | 6,780,865 | |
| -1 | -6,780,865 |
Let's try dividing by 4:
6,780,865 ÷ 4 = 1,695,216.25
If the quotient is a whole number, then 4 and 1,695,216.25 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 | 6,780,865 | |
| -1 | 6,780,865 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 49 | 65 | 91 | 245 | 455 | 637 | 2,129 | 3,185 | 10,645 | 14,903 | 27,677 | 74,515 | 104,321 | 138,385 | 193,739 | 521,605 | 968,695 | 1,356,173 | 6,780,865 |
| -1 | -5 | -7 | -13 | -35 | -49 | -65 | -91 | -245 | -455 | -637 | -2,129 | -3,185 | -10,645 | -14,903 | -27,677 | -74,515 | -104,321 | -138,385 | -193,739 | -521,605 | -968,695 | -1,356,173 | -6,780,865 |
