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 54,281,171, 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 | 54,281,171 | |
| -1 | -54,281,171 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,281,171.
Example:
1 x 54,281,171 = 54,281,171
and
-1 x -54,281,171 = 54,281,171
Notice both answers equal 54,281,171
With that explanation out of the way, let's continue. Next, we take the number 54,281,171 and divide it by 2:
54,281,171 ÷ 2 = 27,140,585.5
If the quotient is a whole number, then 2 and 27,140,585.5 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 | 54,281,171 | |
| -1 | -54,281,171 |
Now, we try dividing 54,281,171 by 3:
54,281,171 ÷ 3 = 18,093,723.6667
If the quotient is a whole number, then 3 and 18,093,723.6667 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 | 54,281,171 | |
| -1 | -54,281,171 |
Let's try dividing by 4:
54,281,171 ÷ 4 = 13,570,292.75
If the quotient is a whole number, then 4 and 13,570,292.75 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 | 54,281,171 | |
| -1 | 54,281,171 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 49 | 287 | 659 | 1,681 | 2,009 | 4,613 | 11,767 | 27,019 | 32,291 | 82,369 | 189,133 | 1,107,779 | 1,323,931 | 7,754,453 | 54,281,171 |
| -1 | -7 | -41 | -49 | -287 | -659 | -1,681 | -2,009 | -4,613 | -11,767 | -27,019 | -32,291 | -82,369 | -189,133 | -1,107,779 | -1,323,931 | -7,754,453 | -54,281,171 |
