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 422,415,635, 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 | 422,415,635 | |
| -1 | -422,415,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 422,415,635.
Example:
1 x 422,415,635 = 422,415,635
and
-1 x -422,415,635 = 422,415,635
Notice both answers equal 422,415,635
With that explanation out of the way, let's continue. Next, we take the number 422,415,635 and divide it by 2:
422,415,635 ÷ 2 = 211,207,817.5
If the quotient is a whole number, then 2 and 211,207,817.5 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 | 422,415,635 | |
| -1 | -422,415,635 |
Now, we try dividing 422,415,635 by 3:
422,415,635 ÷ 3 = 140,805,211.6667
If the quotient is a whole number, then 3 and 140,805,211.6667 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 | 422,415,635 | |
| -1 | -422,415,635 |
Let's try dividing by 4:
422,415,635 ÷ 4 = 105,603,908.75
If the quotient is a whole number, then 4 and 105,603,908.75 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 | 422,415,635 | |
| -1 | 422,415,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 83 | 415 | 643 | 1,583 | 3,215 | 7,915 | 53,369 | 131,389 | 266,845 | 656,945 | 1,017,869 | 5,089,345 | 84,483,127 | 422,415,635 |
| -1 | -5 | -83 | -415 | -643 | -1,583 | -3,215 | -7,915 | -53,369 | -131,389 | -266,845 | -656,945 | -1,017,869 | -5,089,345 | -84,483,127 | -422,415,635 |
