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 522,450,421, 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 | 522,450,421 | |
| -1 | -522,450,421 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 522,450,421.
Example:
1 x 522,450,421 = 522,450,421
and
-1 x -522,450,421 = 522,450,421
Notice both answers equal 522,450,421
With that explanation out of the way, let's continue. Next, we take the number 522,450,421 and divide it by 2:
522,450,421 ÷ 2 = 261,225,210.5
If the quotient is a whole number, then 2 and 261,225,210.5 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 | 522,450,421 | |
| -1 | -522,450,421 |
Now, we try dividing 522,450,421 by 3:
522,450,421 ÷ 3 = 174,150,140.3333
If the quotient is a whole number, then 3 and 174,150,140.3333 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 | 522,450,421 | |
| -1 | -522,450,421 |
Let's try dividing by 4:
522,450,421 ÷ 4 = 130,612,605.25
If the quotient is a whole number, then 4 and 130,612,605.25 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 | 522,450,421 | |
| -1 | 522,450,421 |
If you did it right, you will end up with this table:
| 1 | 61 | 193 | 199 | 223 | 11,773 | 12,139 | 13,603 | 38,407 | 43,039 | 44,377 | 2,342,827 | 2,625,379 | 2,706,997 | 8,564,761 | 522,450,421 |
| -1 | -61 | -193 | -199 | -223 | -11,773 | -12,139 | -13,603 | -38,407 | -43,039 | -44,377 | -2,342,827 | -2,625,379 | -2,706,997 | -8,564,761 | -522,450,421 |
