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 57,240,235, 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 | 57,240,235 | |
| -1 | -57,240,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,240,235.
Example:
1 x 57,240,235 = 57,240,235
and
-1 x -57,240,235 = 57,240,235
Notice both answers equal 57,240,235
With that explanation out of the way, let's continue. Next, we take the number 57,240,235 and divide it by 2:
57,240,235 ÷ 2 = 28,620,117.5
If the quotient is a whole number, then 2 and 28,620,117.5 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 | 57,240,235 | |
| -1 | -57,240,235 |
Now, we try dividing 57,240,235 by 3:
57,240,235 ÷ 3 = 19,080,078.3333
If the quotient is a whole number, then 3 and 19,080,078.3333 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 | 57,240,235 | |
| -1 | -57,240,235 |
Let's try dividing by 4:
57,240,235 ÷ 4 = 14,310,058.75
If the quotient is a whole number, then 4 and 14,310,058.75 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 | 57,240,235 | |
| -1 | 57,240,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 101 | 505 | 1,313 | 6,565 | 8,719 | 43,595 | 113,347 | 566,735 | 880,619 | 4,403,095 | 11,448,047 | 57,240,235 |
| -1 | -5 | -13 | -65 | -101 | -505 | -1,313 | -6,565 | -8,719 | -43,595 | -113,347 | -566,735 | -880,619 | -4,403,095 | -11,448,047 | -57,240,235 |
