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 57,178,285, 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 | 57,178,285 | |
| -1 | -57,178,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,178,285.
Example:
1 x 57,178,285 = 57,178,285
and
-1 x -57,178,285 = 57,178,285
Notice both answers equal 57,178,285
With that explanation out of the way, let's continue. Next, we take the number 57,178,285 and divide it by 2:
57,178,285 ÷ 2 = 28,589,142.5
If the quotient is a whole number, then 2 and 28,589,142.5 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 | 57,178,285 | |
| -1 | -57,178,285 |
Now, we try dividing 57,178,285 by 3:
57,178,285 ÷ 3 = 19,059,428.3333
If the quotient is a whole number, then 3 and 19,059,428.3333 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 | 57,178,285 | |
| -1 | -57,178,285 |
Let's try dividing by 4:
57,178,285 ÷ 4 = 14,294,571.25
If the quotient is a whole number, then 4 and 14,294,571.25 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 | 57,178,285 | |
| -1 | 57,178,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 83 | 145 | 415 | 2,407 | 4,751 | 12,035 | 23,755 | 137,779 | 394,333 | 688,895 | 1,971,665 | 11,435,657 | 57,178,285 |
| -1 | -5 | -29 | -83 | -145 | -415 | -2,407 | -4,751 | -12,035 | -23,755 | -137,779 | -394,333 | -688,895 | -1,971,665 | -11,435,657 | -57,178,285 |
