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 626,225,513, 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 | 626,225,513 | |
| -1 | -626,225,513 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 626,225,513.
Example:
1 x 626,225,513 = 626,225,513
and
-1 x -626,225,513 = 626,225,513
Notice both answers equal 626,225,513
With that explanation out of the way, let's continue. Next, we take the number 626,225,513 and divide it by 2:
626,225,513 ÷ 2 = 313,112,756.5
If the quotient is a whole number, then 2 and 313,112,756.5 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 | 626,225,513 | |
| -1 | -626,225,513 |
Now, we try dividing 626,225,513 by 3:
626,225,513 ÷ 3 = 208,741,837.6667
If the quotient is a whole number, then 3 and 208,741,837.6667 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 | 626,225,513 | |
| -1 | -626,225,513 |
Let's try dividing by 4:
626,225,513 ÷ 4 = 156,556,378.25
If the quotient is a whole number, then 4 and 156,556,378.25 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 | 626,225,513 | |
| -1 | 626,225,513 |
If you did it right, you will end up with this table:
| 1 | 31 | 41 | 283 | 1,271 | 1,741 | 8,773 | 11,603 | 53,971 | 71,381 | 359,693 | 492,703 | 2,212,811 | 15,273,793 | 20,200,823 | 626,225,513 |
| -1 | -31 | -41 | -283 | -1,271 | -1,741 | -8,773 | -11,603 | -53,971 | -71,381 | -359,693 | -492,703 | -2,212,811 | -15,273,793 | -20,200,823 | -626,225,513 |
