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 8,274,539, 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 | 8,274,539 | |
| -1 | -8,274,539 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,274,539.
Example:
1 x 8,274,539 = 8,274,539
and
-1 x -8,274,539 = 8,274,539
Notice both answers equal 8,274,539
With that explanation out of the way, let's continue. Next, we take the number 8,274,539 and divide it by 2:
8,274,539 ÷ 2 = 4,137,269.5
If the quotient is a whole number, then 2 and 4,137,269.5 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 | 8,274,539 | |
| -1 | -8,274,539 |
Now, we try dividing 8,274,539 by 3:
8,274,539 ÷ 3 = 2,758,179.6667
If the quotient is a whole number, then 3 and 2,758,179.6667 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 | 8,274,539 | |
| -1 | -8,274,539 |
Let's try dividing by 4:
8,274,539 ÷ 4 = 2,068,634.75
If the quotient is a whole number, then 4 and 2,068,634.75 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 | 8,274,539 | |
| -1 | 8,274,539 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 79 | 91 | 553 | 1,027 | 1,151 | 7,189 | 8,057 | 14,963 | 90,929 | 104,741 | 636,503 | 1,182,077 | 8,274,539 |
| -1 | -7 | -13 | -79 | -91 | -553 | -1,027 | -1,151 | -7,189 | -8,057 | -14,963 | -90,929 | -104,741 | -636,503 | -1,182,077 | -8,274,539 |
