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 55,765,015, 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 | 55,765,015 | |
| -1 | -55,765,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,765,015.
Example:
1 x 55,765,015 = 55,765,015
and
-1 x -55,765,015 = 55,765,015
Notice both answers equal 55,765,015
With that explanation out of the way, let's continue. Next, we take the number 55,765,015 and divide it by 2:
55,765,015 ÷ 2 = 27,882,507.5
If the quotient is a whole number, then 2 and 27,882,507.5 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 | 55,765,015 | |
| -1 | -55,765,015 |
Now, we try dividing 55,765,015 by 3:
55,765,015 ÷ 3 = 18,588,338.3333
If the quotient is a whole number, then 3 and 18,588,338.3333 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 | 55,765,015 | |
| -1 | -55,765,015 |
Let's try dividing by 4:
55,765,015 ÷ 4 = 13,941,253.75
If the quotient is a whole number, then 4 and 13,941,253.75 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 | 55,765,015 | |
| -1 | 55,765,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 307 | 1,535 | 2,137 | 5,219 | 10,685 | 26,095 | 36,329 | 181,645 | 656,059 | 3,280,295 | 11,153,003 | 55,765,015 |
| -1 | -5 | -17 | -85 | -307 | -1,535 | -2,137 | -5,219 | -10,685 | -26,095 | -36,329 | -181,645 | -656,059 | -3,280,295 | -11,153,003 | -55,765,015 |
