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 7,837,459, 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 | 7,837,459 | |
| -1 | -7,837,459 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,837,459.
Example:
1 x 7,837,459 = 7,837,459
and
-1 x -7,837,459 = 7,837,459
Notice both answers equal 7,837,459
With that explanation out of the way, let's continue. Next, we take the number 7,837,459 and divide it by 2:
7,837,459 ÷ 2 = 3,918,729.5
If the quotient is a whole number, then 2 and 3,918,729.5 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 | 7,837,459 | |
| -1 | -7,837,459 |
Now, we try dividing 7,837,459 by 3:
7,837,459 ÷ 3 = 2,612,486.3333
If the quotient is a whole number, then 3 and 2,612,486.3333 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 | 7,837,459 | |
| -1 | -7,837,459 |
Let's try dividing by 4:
7,837,459 ÷ 4 = 1,959,364.75
If the quotient is a whole number, then 4 and 1,959,364.75 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 | 7,837,459 | |
| -1 | 7,837,459 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 67 | 119 | 469 | 983 | 1,139 | 6,881 | 7,973 | 16,711 | 65,861 | 116,977 | 461,027 | 1,119,637 | 7,837,459 |
| -1 | -7 | -17 | -67 | -119 | -469 | -983 | -1,139 | -6,881 | -7,973 | -16,711 | -65,861 | -116,977 | -461,027 | -1,119,637 | -7,837,459 |
