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 57,999,865, 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 | 57,999,865 | |
| -1 | -57,999,865 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,999,865.
Example:
1 x 57,999,865 = 57,999,865
and
-1 x -57,999,865 = 57,999,865
Notice both answers equal 57,999,865
With that explanation out of the way, let's continue. Next, we take the number 57,999,865 and divide it by 2:
57,999,865 ÷ 2 = 28,999,932.5
If the quotient is a whole number, then 2 and 28,999,932.5 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 | 57,999,865 | |
| -1 | -57,999,865 |
Now, we try dividing 57,999,865 by 3:
57,999,865 ÷ 3 = 19,333,288.3333
If the quotient is a whole number, then 3 and 19,333,288.3333 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 | 57,999,865 | |
| -1 | -57,999,865 |
Let's try dividing by 4:
57,999,865 ÷ 4 = 14,499,966.25
If the quotient is a whole number, then 4 and 14,499,966.25 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 | 57,999,865 | |
| -1 | 57,999,865 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 150,649 | 753,245 | 1,054,543 | 1,657,139 | 5,272,715 | 8,285,695 | 11,599,973 | 57,999,865 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -150,649 | -753,245 | -1,054,543 | -1,657,139 | -5,272,715 | -8,285,695 | -11,599,973 | -57,999,865 |
