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 4,894,715, 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 | 4,894,715 | |
| -1 | -4,894,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,894,715.
Example:
1 x 4,894,715 = 4,894,715
and
-1 x -4,894,715 = 4,894,715
Notice both answers equal 4,894,715
With that explanation out of the way, let's continue. Next, we take the number 4,894,715 and divide it by 2:
4,894,715 ÷ 2 = 2,447,357.5
If the quotient is a whole number, then 2 and 2,447,357.5 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 | 4,894,715 | |
| -1 | -4,894,715 |
Now, we try dividing 4,894,715 by 3:
4,894,715 ÷ 3 = 1,631,571.6667
If the quotient is a whole number, then 3 and 1,631,571.6667 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 | 4,894,715 | |
| -1 | -4,894,715 |
Let's try dividing by 4:
4,894,715 ÷ 4 = 1,223,678.75
If the quotient is a whole number, then 4 and 1,223,678.75 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 | 4,894,715 | |
| -1 | 4,894,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 107 | 535 | 749 | 1,307 | 3,745 | 6,535 | 9,149 | 45,745 | 139,849 | 699,245 | 978,943 | 4,894,715 |
| -1 | -5 | -7 | -35 | -107 | -535 | -749 | -1,307 | -3,745 | -6,535 | -9,149 | -45,745 | -139,849 | -699,245 | -978,943 | -4,894,715 |
