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 522,224,207, 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 | 522,224,207 | |
| -1 | -522,224,207 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 522,224,207.
Example:
1 x 522,224,207 = 522,224,207
and
-1 x -522,224,207 = 522,224,207
Notice both answers equal 522,224,207
With that explanation out of the way, let's continue. Next, we take the number 522,224,207 and divide it by 2:
522,224,207 ÷ 2 = 261,112,103.5
If the quotient is a whole number, then 2 and 261,112,103.5 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 | 522,224,207 | |
| -1 | -522,224,207 |
Now, we try dividing 522,224,207 by 3:
522,224,207 ÷ 3 = 174,074,735.6667
If the quotient is a whole number, then 3 and 174,074,735.6667 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 | 522,224,207 | |
| -1 | -522,224,207 |
Let's try dividing by 4:
522,224,207 ÷ 4 = 130,556,051.75
If the quotient is a whole number, then 4 and 130,556,051.75 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 | 522,224,207 | |
| -1 | 522,224,207 |
If you did it right, you will end up with this table:
| 1 | 17 | 43 | 79 | 731 | 1,343 | 3,397 | 9,043 | 57,749 | 153,731 | 388,849 | 714,397 | 6,610,433 | 12,144,749 | 30,719,071 | 522,224,207 |
| -1 | -17 | -43 | -79 | -731 | -1,343 | -3,397 | -9,043 | -57,749 | -153,731 | -388,849 | -714,397 | -6,610,433 | -12,144,749 | -30,719,071 | -522,224,207 |
