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 522,420,215, 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 | 522,420,215 | |
| -1 | -522,420,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 522,420,215.
Example:
1 x 522,420,215 = 522,420,215
and
-1 x -522,420,215 = 522,420,215
Notice both answers equal 522,420,215
With that explanation out of the way, let's continue. Next, we take the number 522,420,215 and divide it by 2:
522,420,215 ÷ 2 = 261,210,107.5
If the quotient is a whole number, then 2 and 261,210,107.5 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 | 522,420,215 | |
| -1 | -522,420,215 |
Now, we try dividing 522,420,215 by 3:
522,420,215 ÷ 3 = 174,140,071.6667
If the quotient is a whole number, then 3 and 174,140,071.6667 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 | 522,420,215 | |
| -1 | -522,420,215 |
Let's try dividing by 4:
522,420,215 ÷ 4 = 130,605,053.75
If the quotient is a whole number, then 4 and 130,605,053.75 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 | 522,420,215 | |
| -1 | 522,420,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 127 | 155 | 635 | 3,937 | 19,685 | 26,539 | 132,695 | 822,709 | 3,370,453 | 4,113,545 | 16,852,265 | 104,484,043 | 522,420,215 |
| -1 | -5 | -31 | -127 | -155 | -635 | -3,937 | -19,685 | -26,539 | -132,695 | -822,709 | -3,370,453 | -4,113,545 | -16,852,265 | -104,484,043 | -522,420,215 |
