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 7,956,739, 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 | 7,956,739 | |
| -1 | -7,956,739 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,956,739.
Example:
1 x 7,956,739 = 7,956,739
and
-1 x -7,956,739 = 7,956,739
Notice both answers equal 7,956,739
With that explanation out of the way, let's continue. Next, we take the number 7,956,739 and divide it by 2:
7,956,739 ÷ 2 = 3,978,369.5
If the quotient is a whole number, then 2 and 3,978,369.5 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 | 7,956,739 | |
| -1 | -7,956,739 |
Now, we try dividing 7,956,739 by 3:
7,956,739 ÷ 3 = 2,652,246.3333
If the quotient is a whole number, then 3 and 2,652,246.3333 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 | 7,956,739 | |
| -1 | -7,956,739 |
Let's try dividing by 4:
7,956,739 ÷ 4 = 1,989,184.75
If the quotient is a whole number, then 4 and 1,989,184.75 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 | 7,956,739 | |
| -1 | 7,956,739 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 37 | 217 | 259 | 991 | 1,147 | 6,937 | 8,029 | 30,721 | 36,667 | 215,047 | 256,669 | 1,136,677 | 7,956,739 |
| -1 | -7 | -31 | -37 | -217 | -259 | -991 | -1,147 | -6,937 | -8,029 | -30,721 | -36,667 | -215,047 | -256,669 | -1,136,677 | -7,956,739 |
