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 57,577,949, 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 | 57,577,949 | |
| -1 | -57,577,949 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,577,949.
Example:
1 x 57,577,949 = 57,577,949
and
-1 x -57,577,949 = 57,577,949
Notice both answers equal 57,577,949
With that explanation out of the way, let's continue. Next, we take the number 57,577,949 and divide it by 2:
57,577,949 ÷ 2 = 28,788,974.5
If the quotient is a whole number, then 2 and 28,788,974.5 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 | 57,577,949 | |
| -1 | -57,577,949 |
Now, we try dividing 57,577,949 by 3:
57,577,949 ÷ 3 = 19,192,649.6667
If the quotient is a whole number, then 3 and 19,192,649.6667 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 | 57,577,949 | |
| -1 | -57,577,949 |
Let's try dividing by 4:
57,577,949 ÷ 4 = 14,394,487.25
If the quotient is a whole number, then 4 and 14,394,487.25 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 | 57,577,949 | |
| -1 | 57,577,949 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 137 | 143 | 1,507 | 1,781 | 2,939 | 19,591 | 32,329 | 38,207 | 402,643 | 420,277 | 4,429,073 | 5,234,359 | 57,577,949 |
| -1 | -11 | -13 | -137 | -143 | -1,507 | -1,781 | -2,939 | -19,591 | -32,329 | -38,207 | -402,643 | -420,277 | -4,429,073 | -5,234,359 | -57,577,949 |
