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 57,271,265, 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 | 57,271,265 | |
| -1 | -57,271,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,271,265.
Example:
1 x 57,271,265 = 57,271,265
and
-1 x -57,271,265 = 57,271,265
Notice both answers equal 57,271,265
With that explanation out of the way, let's continue. Next, we take the number 57,271,265 and divide it by 2:
57,271,265 ÷ 2 = 28,635,632.5
If the quotient is a whole number, then 2 and 28,635,632.5 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 | 57,271,265 | |
| -1 | -57,271,265 |
Now, we try dividing 57,271,265 by 3:
57,271,265 ÷ 3 = 19,090,421.6667
If the quotient is a whole number, then 3 and 19,090,421.6667 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 | 57,271,265 | |
| -1 | -57,271,265 |
Let's try dividing by 4:
57,271,265 ÷ 4 = 14,317,816.25
If the quotient is a whole number, then 4 and 14,317,816.25 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 | 57,271,265 | |
| -1 | 57,271,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 67 | 115 | 335 | 1,541 | 7,433 | 7,705 | 37,165 | 170,959 | 498,011 | 854,795 | 2,490,055 | 11,454,253 | 57,271,265 |
| -1 | -5 | -23 | -67 | -115 | -335 | -1,541 | -7,433 | -7,705 | -37,165 | -170,959 | -498,011 | -854,795 | -2,490,055 | -11,454,253 | -57,271,265 |
