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 55,757,663, 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 | 55,757,663 | |
| -1 | -55,757,663 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,757,663.
Example:
1 x 55,757,663 = 55,757,663
and
-1 x -55,757,663 = 55,757,663
Notice both answers equal 55,757,663
With that explanation out of the way, let's continue. Next, we take the number 55,757,663 and divide it by 2:
55,757,663 ÷ 2 = 27,878,831.5
If the quotient is a whole number, then 2 and 27,878,831.5 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 | 55,757,663 | |
| -1 | -55,757,663 |
Now, we try dividing 55,757,663 by 3:
55,757,663 ÷ 3 = 18,585,887.6667
If the quotient is a whole number, then 3 and 18,585,887.6667 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 | 55,757,663 | |
| -1 | -55,757,663 |
Let's try dividing by 4:
55,757,663 ÷ 4 = 13,939,415.75
If the quotient is a whole number, then 4 and 13,939,415.75 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 | 55,757,663 | |
| -1 | 55,757,663 |
If you did it right, you will end up with this table:
| 1 | 13 | 41 | 169 | 533 | 619 | 2,197 | 6,929 | 8,047 | 25,379 | 90,077 | 104,611 | 329,927 | 1,359,943 | 4,289,051 | 55,757,663 |
| -1 | -13 | -41 | -169 | -533 | -619 | -2,197 | -6,929 | -8,047 | -25,379 | -90,077 | -104,611 | -329,927 | -1,359,943 | -4,289,051 | -55,757,663 |
