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 553,216,015, 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 | 553,216,015 | |
| -1 | -553,216,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 553,216,015.
Example:
1 x 553,216,015 = 553,216,015
and
-1 x -553,216,015 = 553,216,015
Notice both answers equal 553,216,015
With that explanation out of the way, let's continue. Next, we take the number 553,216,015 and divide it by 2:
553,216,015 ÷ 2 = 276,608,007.5
If the quotient is a whole number, then 2 and 276,608,007.5 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 | 553,216,015 | |
| -1 | -553,216,015 |
Now, we try dividing 553,216,015 by 3:
553,216,015 ÷ 3 = 184,405,338.3333
If the quotient is a whole number, then 3 and 184,405,338.3333 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 | 553,216,015 | |
| -1 | -553,216,015 |
Let's try dividing by 4:
553,216,015 ÷ 4 = 138,304,003.75
If the quotient is a whole number, then 4 and 138,304,003.75 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 | 553,216,015 | |
| -1 | 553,216,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 61 | 305 | 671 | 3,355 | 164,893 | 824,465 | 1,813,823 | 9,069,115 | 10,058,473 | 50,292,365 | 110,643,203 | 553,216,015 |
| -1 | -5 | -11 | -55 | -61 | -305 | -671 | -3,355 | -164,893 | -824,465 | -1,813,823 | -9,069,115 | -10,058,473 | -50,292,365 | -110,643,203 | -553,216,015 |
