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 624,626,513, 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 | 624,626,513 | |
| -1 | -624,626,513 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 624,626,513.
Example:
1 x 624,626,513 = 624,626,513
and
-1 x -624,626,513 = 624,626,513
Notice both answers equal 624,626,513
With that explanation out of the way, let's continue. Next, we take the number 624,626,513 and divide it by 2:
624,626,513 ÷ 2 = 312,313,256.5
If the quotient is a whole number, then 2 and 312,313,256.5 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 | 624,626,513 | |
| -1 | -624,626,513 |
Now, we try dividing 624,626,513 by 3:
624,626,513 ÷ 3 = 208,208,837.6667
If the quotient is a whole number, then 3 and 208,208,837.6667 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 | 624,626,513 | |
| -1 | -624,626,513 |
Let's try dividing by 4:
624,626,513 ÷ 4 = 156,156,628.25
If the quotient is a whole number, then 4 and 156,156,628.25 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 | 624,626,513 | |
| -1 | 624,626,513 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 127 | 287 | 889 | 5,207 | 17,137 | 36,449 | 119,959 | 702,617 | 2,176,399 | 4,918,319 | 15,234,793 | 89,232,359 | 624,626,513 |
| -1 | -7 | -41 | -127 | -287 | -889 | -5,207 | -17,137 | -36,449 | -119,959 | -702,617 | -2,176,399 | -4,918,319 | -15,234,793 | -89,232,359 | -624,626,513 |
