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 5,400,541, 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 | 5,400,541 | |
| -1 | -5,400,541 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,400,541.
Example:
1 x 5,400,541 = 5,400,541
and
-1 x -5,400,541 = 5,400,541
Notice both answers equal 5,400,541
With that explanation out of the way, let's continue. Next, we take the number 5,400,541 and divide it by 2:
5,400,541 ÷ 2 = 2,700,270.5
If the quotient is a whole number, then 2 and 2,700,270.5 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 | 5,400,541 | |
| -1 | -5,400,541 |
Now, we try dividing 5,400,541 by 3:
5,400,541 ÷ 3 = 1,800,180.3333
If the quotient is a whole number, then 3 and 1,800,180.3333 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 | 5,400,541 | |
| -1 | -5,400,541 |
Let's try dividing by 4:
5,400,541 ÷ 4 = 1,350,135.25
If the quotient is a whole number, then 4 and 1,350,135.25 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 | 5,400,541 | |
| -1 | 5,400,541 |
If you did it right, you will end up with this table:
| 1 | 19 | 31 | 53 | 173 | 589 | 1,007 | 1,643 | 3,287 | 5,363 | 9,169 | 31,217 | 101,897 | 174,211 | 284,239 | 5,400,541 |
| -1 | -19 | -31 | -53 | -173 | -589 | -1,007 | -1,643 | -3,287 | -5,363 | -9,169 | -31,217 | -101,897 | -174,211 | -284,239 | -5,400,541 |
