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 6,908,815, 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 | 6,908,815 | |
| -1 | -6,908,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,908,815.
Example:
1 x 6,908,815 = 6,908,815
and
-1 x -6,908,815 = 6,908,815
Notice both answers equal 6,908,815
With that explanation out of the way, let's continue. Next, we take the number 6,908,815 and divide it by 2:
6,908,815 ÷ 2 = 3,454,407.5
If the quotient is a whole number, then 2 and 3,454,407.5 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 | 6,908,815 | |
| -1 | -6,908,815 |
Now, we try dividing 6,908,815 by 3:
6,908,815 ÷ 3 = 2,302,938.3333
If the quotient is a whole number, then 3 and 2,302,938.3333 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 | 6,908,815 | |
| -1 | -6,908,815 |
Let's try dividing by 4:
6,908,815 ÷ 4 = 1,727,203.75
If the quotient is a whole number, then 4 and 1,727,203.75 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 | 6,908,815 | |
| -1 | 6,908,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 31 | 53 | 145 | 155 | 265 | 841 | 899 | 1,537 | 1,643 | 4,205 | 4,495 | 7,685 | 8,215 | 26,071 | 44,573 | 47,647 | 130,355 | 222,865 | 238,235 | 1,381,763 | 6,908,815 |
| -1 | -5 | -29 | -31 | -53 | -145 | -155 | -265 | -841 | -899 | -1,537 | -1,643 | -4,205 | -4,495 | -7,685 | -8,215 | -26,071 | -44,573 | -47,647 | -130,355 | -222,865 | -238,235 | -1,381,763 | -6,908,815 |
