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 5,457,515, 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 | 5,457,515 | |
| -1 | -5,457,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,457,515.
Example:
1 x 5,457,515 = 5,457,515
and
-1 x -5,457,515 = 5,457,515
Notice both answers equal 5,457,515
With that explanation out of the way, let's continue. Next, we take the number 5,457,515 and divide it by 2:
5,457,515 ÷ 2 = 2,728,757.5
If the quotient is a whole number, then 2 and 2,728,757.5 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 | 5,457,515 | |
| -1 | -5,457,515 |
Now, we try dividing 5,457,515 by 3:
5,457,515 ÷ 3 = 1,819,171.6667
If the quotient is a whole number, then 3 and 1,819,171.6667 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 | 5,457,515 | |
| -1 | -5,457,515 |
Let's try dividing by 4:
5,457,515 ÷ 4 = 1,364,378.75
If the quotient is a whole number, then 4 and 1,364,378.75 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 | 5,457,515 | |
| -1 | 5,457,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 211 | 739 | 1,055 | 1,477 | 3,695 | 5,173 | 7,385 | 25,865 | 155,929 | 779,645 | 1,091,503 | 5,457,515 |
| -1 | -5 | -7 | -35 | -211 | -739 | -1,055 | -1,477 | -3,695 | -5,173 | -7,385 | -25,865 | -155,929 | -779,645 | -1,091,503 | -5,457,515 |
