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 7,678,069, 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 | 7,678,069 | |
| -1 | -7,678,069 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,678,069.
Example:
1 x 7,678,069 = 7,678,069
and
-1 x -7,678,069 = 7,678,069
Notice both answers equal 7,678,069
With that explanation out of the way, let's continue. Next, we take the number 7,678,069 and divide it by 2:
7,678,069 ÷ 2 = 3,839,034.5
If the quotient is a whole number, then 2 and 3,839,034.5 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 | 7,678,069 | |
| -1 | -7,678,069 |
Now, we try dividing 7,678,069 by 3:
7,678,069 ÷ 3 = 2,559,356.3333
If the quotient is a whole number, then 3 and 2,559,356.3333 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 | 7,678,069 | |
| -1 | -7,678,069 |
Let's try dividing by 4:
7,678,069 ÷ 4 = 1,919,517.25
If the quotient is a whole number, then 4 and 1,919,517.25 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 | 7,678,069 | |
| -1 | 7,678,069 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 109 | 203 | 347 | 763 | 2,429 | 3,161 | 10,063 | 22,127 | 37,823 | 70,441 | 264,761 | 1,096,867 | 7,678,069 |
| -1 | -7 | -29 | -109 | -203 | -347 | -763 | -2,429 | -3,161 | -10,063 | -22,127 | -37,823 | -70,441 | -264,761 | -1,096,867 | -7,678,069 |
