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 500,153,255, 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 | 500,153,255 | |
| -1 | -500,153,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 500,153,255.
Example:
1 x 500,153,255 = 500,153,255
and
-1 x -500,153,255 = 500,153,255
Notice both answers equal 500,153,255
With that explanation out of the way, let's continue. Next, we take the number 500,153,255 and divide it by 2:
500,153,255 ÷ 2 = 250,076,627.5
If the quotient is a whole number, then 2 and 250,076,627.5 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 | 500,153,255 | |
| -1 | -500,153,255 |
Now, we try dividing 500,153,255 by 3:
500,153,255 ÷ 3 = 166,717,751.6667
If the quotient is a whole number, then 3 and 166,717,751.6667 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 | 500,153,255 | |
| -1 | -500,153,255 |
Let's try dividing by 4:
500,153,255 ÷ 4 = 125,038,313.75
If the quotient is a whole number, then 4 and 125,038,313.75 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 | 500,153,255 | |
| -1 | 500,153,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 113 | 565 | 791 | 3,955 | 126,461 | 632,305 | 885,227 | 4,426,135 | 14,290,093 | 71,450,465 | 100,030,651 | 500,153,255 |
| -1 | -5 | -7 | -35 | -113 | -565 | -791 | -3,955 | -126,461 | -632,305 | -885,227 | -4,426,135 | -14,290,093 | -71,450,465 | -100,030,651 | -500,153,255 |
