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 624,700,255, 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 | 624,700,255 | |
| -1 | -624,700,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 624,700,255.
Example:
1 x 624,700,255 = 624,700,255
and
-1 x -624,700,255 = 624,700,255
Notice both answers equal 624,700,255
With that explanation out of the way, let's continue. Next, we take the number 624,700,255 and divide it by 2:
624,700,255 ÷ 2 = 312,350,127.5
If the quotient is a whole number, then 2 and 312,350,127.5 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 | 624,700,255 | |
| -1 | -624,700,255 |
Now, we try dividing 624,700,255 by 3:
624,700,255 ÷ 3 = 208,233,418.3333
If the quotient is a whole number, then 3 and 208,233,418.3333 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 | 624,700,255 | |
| -1 | -624,700,255 |
Let's try dividing by 4:
624,700,255 ÷ 4 = 156,175,063.75
If the quotient is a whole number, then 4 and 156,175,063.75 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 | 624,700,255 | |
| -1 | 624,700,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 109 | 545 | 877 | 1,307 | 4,385 | 6,535 | 95,593 | 142,463 | 477,965 | 712,315 | 1,146,239 | 5,731,195 | 124,940,051 | 624,700,255 |
| -1 | -5 | -109 | -545 | -877 | -1,307 | -4,385 | -6,535 | -95,593 | -142,463 | -477,965 | -712,315 | -1,146,239 | -5,731,195 | -124,940,051 | -624,700,255 |
