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 822,422,465, 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 | 822,422,465 | |
| -1 | -822,422,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 822,422,465.
Example:
1 x 822,422,465 = 822,422,465
and
-1 x -822,422,465 = 822,422,465
Notice both answers equal 822,422,465
With that explanation out of the way, let's continue. Next, we take the number 822,422,465 and divide it by 2:
822,422,465 ÷ 2 = 411,211,232.5
If the quotient is a whole number, then 2 and 411,211,232.5 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 | 822,422,465 | |
| -1 | -822,422,465 |
Now, we try dividing 822,422,465 by 3:
822,422,465 ÷ 3 = 274,140,821.6667
If the quotient is a whole number, then 3 and 274,140,821.6667 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 | 822,422,465 | |
| -1 | -822,422,465 |
Let's try dividing by 4:
822,422,465 ÷ 4 = 205,605,616.25
If the quotient is a whole number, then 4 and 205,605,616.25 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 | 822,422,465 | |
| -1 | 822,422,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 71 | 265 | 355 | 3,763 | 18,815 | 43,711 | 218,555 | 2,316,683 | 3,103,481 | 11,583,415 | 15,517,405 | 164,484,493 | 822,422,465 |
| -1 | -5 | -53 | -71 | -265 | -355 | -3,763 | -18,815 | -43,711 | -218,555 | -2,316,683 | -3,103,481 | -11,583,415 | -15,517,405 | -164,484,493 | -822,422,465 |
