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 5,141,647, 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 | 5,141,647 | |
| -1 | -5,141,647 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,141,647.
Example:
1 x 5,141,647 = 5,141,647
and
-1 x -5,141,647 = 5,141,647
Notice both answers equal 5,141,647
With that explanation out of the way, let's continue. Next, we take the number 5,141,647 and divide it by 2:
5,141,647 ÷ 2 = 2,570,823.5
If the quotient is a whole number, then 2 and 2,570,823.5 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 | 5,141,647 | |
| -1 | -5,141,647 |
Now, we try dividing 5,141,647 by 3:
5,141,647 ÷ 3 = 1,713,882.3333
If the quotient is a whole number, then 3 and 1,713,882.3333 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 | 5,141,647 | |
| -1 | -5,141,647 |
Let's try dividing by 4:
5,141,647 ÷ 4 = 1,285,411.75
If the quotient is a whole number, then 4 and 1,285,411.75 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 | 5,141,647 | |
| -1 | 5,141,647 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 67 | 133 | 469 | 577 | 1,273 | 4,039 | 8,911 | 10,963 | 38,659 | 76,741 | 270,613 | 734,521 | 5,141,647 |
| -1 | -7 | -19 | -67 | -133 | -469 | -577 | -1,273 | -4,039 | -8,911 | -10,963 | -38,659 | -76,741 | -270,613 | -734,521 | -5,141,647 |
