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 57,111,565, 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 | 57,111,565 | |
| -1 | -57,111,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 57,111,565.
Example:
1 x 57,111,565 = 57,111,565
and
-1 x -57,111,565 = 57,111,565
Notice both answers equal 57,111,565
With that explanation out of the way, let's continue. Next, we take the number 57,111,565 and divide it by 2:
57,111,565 ÷ 2 = 28,555,782.5
If the quotient is a whole number, then 2 and 28,555,782.5 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 | 57,111,565 | |
| -1 | -57,111,565 |
Now, we try dividing 57,111,565 by 3:
57,111,565 ÷ 3 = 19,037,188.3333
If the quotient is a whole number, then 3 and 19,037,188.3333 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 | 57,111,565 | |
| -1 | -57,111,565 |
Let's try dividing by 4:
57,111,565 ÷ 4 = 14,277,891.25
If the quotient is a whole number, then 4 and 14,277,891.25 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 | 57,111,565 | |
| -1 | 57,111,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 41 | 205 | 287 | 1,435 | 39,799 | 198,995 | 278,593 | 1,392,965 | 1,631,759 | 8,158,795 | 11,422,313 | 57,111,565 |
| -1 | -5 | -7 | -35 | -41 | -205 | -287 | -1,435 | -39,799 | -198,995 | -278,593 | -1,392,965 | -1,631,759 | -8,158,795 | -11,422,313 | -57,111,565 |
