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 455,002,015, 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 | 455,002,015 | |
| -1 | -455,002,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 455,002,015.
Example:
1 x 455,002,015 = 455,002,015
and
-1 x -455,002,015 = 455,002,015
Notice both answers equal 455,002,015
With that explanation out of the way, let's continue. Next, we take the number 455,002,015 and divide it by 2:
455,002,015 ÷ 2 = 227,501,007.5
If the quotient is a whole number, then 2 and 227,501,007.5 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 | 455,002,015 | |
| -1 | -455,002,015 |
Now, we try dividing 455,002,015 by 3:
455,002,015 ÷ 3 = 151,667,338.3333
If the quotient is a whole number, then 3 and 151,667,338.3333 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 | 455,002,015 | |
| -1 | -455,002,015 |
Let's try dividing by 4:
455,002,015 ÷ 4 = 113,750,503.75
If the quotient is a whole number, then 4 and 113,750,503.75 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 | 455,002,015 | |
| -1 | 455,002,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 347 | 1,735 | 4,511 | 20,173 | 22,555 | 100,865 | 262,249 | 1,311,245 | 7,000,031 | 35,000,155 | 91,000,403 | 455,002,015 |
| -1 | -5 | -13 | -65 | -347 | -1,735 | -4,511 | -20,173 | -22,555 | -100,865 | -262,249 | -1,311,245 | -7,000,031 | -35,000,155 | -91,000,403 | -455,002,015 |
