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 57,022,021, 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 | 57,022,021 | |
| -1 | -57,022,021 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,022,021.
Example:
1 x 57,022,021 = 57,022,021
and
-1 x -57,022,021 = 57,022,021
Notice both answers equal 57,022,021
With that explanation out of the way, let's continue. Next, we take the number 57,022,021 and divide it by 2:
57,022,021 ÷ 2 = 28,511,010.5
If the quotient is a whole number, then 2 and 28,511,010.5 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 | 57,022,021 | |
| -1 | -57,022,021 |
Now, we try dividing 57,022,021 by 3:
57,022,021 ÷ 3 = 19,007,340.3333
If the quotient is a whole number, then 3 and 19,007,340.3333 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 | 57,022,021 | |
| -1 | -57,022,021 |
Let's try dividing by 4:
57,022,021 ÷ 4 = 14,255,505.25
If the quotient is a whole number, then 4 and 14,255,505.25 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 | 57,022,021 | |
| -1 | 57,022,021 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 41 | 133 | 287 | 779 | 5,453 | 10,457 | 73,199 | 198,683 | 428,737 | 1,390,781 | 3,001,159 | 8,146,003 | 57,022,021 |
| -1 | -7 | -19 | -41 | -133 | -287 | -779 | -5,453 | -10,457 | -73,199 | -198,683 | -428,737 | -1,390,781 | -3,001,159 | -8,146,003 | -57,022,021 |
