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 502,250,005, 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 | 502,250,005 | |
| -1 | -502,250,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 502,250,005.
Example:
1 x 502,250,005 = 502,250,005
and
-1 x -502,250,005 = 502,250,005
Notice both answers equal 502,250,005
With that explanation out of the way, let's continue. Next, we take the number 502,250,005 and divide it by 2:
502,250,005 ÷ 2 = 251,125,002.5
If the quotient is a whole number, then 2 and 251,125,002.5 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 | 502,250,005 | |
| -1 | -502,250,005 |
Now, we try dividing 502,250,005 by 3:
502,250,005 ÷ 3 = 167,416,668.3333
If the quotient is a whole number, then 3 and 167,416,668.3333 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 | 502,250,005 | |
| -1 | -502,250,005 |
Let's try dividing by 4:
502,250,005 ÷ 4 = 125,562,501.25
If the quotient is a whole number, then 4 and 125,562,501.25 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 | 502,250,005 | |
| -1 | 502,250,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 79 | 283 | 395 | 1,415 | 4,493 | 22,357 | 22,465 | 111,785 | 354,947 | 1,271,519 | 1,774,735 | 6,357,595 | 100,450,001 | 502,250,005 |
| -1 | -5 | -79 | -283 | -395 | -1,415 | -4,493 | -22,357 | -22,465 | -111,785 | -354,947 | -1,271,519 | -1,774,735 | -6,357,595 | -100,450,001 | -502,250,005 |
