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 30,422,455, 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 | 30,422,455 | |
| -1 | -30,422,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,422,455.
Example:
1 x 30,422,455 = 30,422,455
and
-1 x -30,422,455 = 30,422,455
Notice both answers equal 30,422,455
With that explanation out of the way, let's continue. Next, we take the number 30,422,455 and divide it by 2:
30,422,455 ÷ 2 = 15,211,227.5
If the quotient is a whole number, then 2 and 15,211,227.5 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 | 30,422,455 | |
| -1 | -30,422,455 |
Now, we try dividing 30,422,455 by 3:
30,422,455 ÷ 3 = 10,140,818.3333
If the quotient is a whole number, then 3 and 10,140,818.3333 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 | 30,422,455 | |
| -1 | -30,422,455 |
Let's try dividing by 4:
30,422,455 ÷ 4 = 7,605,613.75
If the quotient is a whole number, then 4 and 7,605,613.75 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 | 30,422,455 | |
| -1 | 30,422,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 251 | 1,255 | 1,757 | 3,463 | 8,785 | 17,315 | 24,241 | 121,205 | 869,213 | 4,346,065 | 6,084,491 | 30,422,455 |
| -1 | -5 | -7 | -35 | -251 | -1,255 | -1,757 | -3,463 | -8,785 | -17,315 | -24,241 | -121,205 | -869,213 | -4,346,065 | -6,084,491 | -30,422,455 |
