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 5,400,115, 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 | 5,400,115 | |
| -1 | -5,400,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,400,115.
Example:
1 x 5,400,115 = 5,400,115
and
-1 x -5,400,115 = 5,400,115
Notice both answers equal 5,400,115
With that explanation out of the way, let's continue. Next, we take the number 5,400,115 and divide it by 2:
5,400,115 ÷ 2 = 2,700,057.5
If the quotient is a whole number, then 2 and 2,700,057.5 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 | 5,400,115 | |
| -1 | -5,400,115 |
Now, we try dividing 5,400,115 by 3:
5,400,115 ÷ 3 = 1,800,038.3333
If the quotient is a whole number, then 3 and 1,800,038.3333 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 | 5,400,115 | |
| -1 | -5,400,115 |
Let's try dividing by 4:
5,400,115 ÷ 4 = 1,350,028.75
If the quotient is a whole number, then 4 and 1,350,028.75 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 | 5,400,115 | |
| -1 | 5,400,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 277 | 557 | 1,385 | 1,939 | 2,785 | 3,899 | 9,695 | 19,495 | 154,289 | 771,445 | 1,080,023 | 5,400,115 |
| -1 | -5 | -7 | -35 | -277 | -557 | -1,385 | -1,939 | -2,785 | -3,899 | -9,695 | -19,495 | -154,289 | -771,445 | -1,080,023 | -5,400,115 |
