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 30,430,465, 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 | 30,430,465 | |
| -1 | -30,430,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,430,465.
Example:
1 x 30,430,465 = 30,430,465
and
-1 x -30,430,465 = 30,430,465
Notice both answers equal 30,430,465
With that explanation out of the way, let's continue. Next, we take the number 30,430,465 and divide it by 2:
30,430,465 ÷ 2 = 15,215,232.5
If the quotient is a whole number, then 2 and 15,215,232.5 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 | 30,430,465 | |
| -1 | -30,430,465 |
Now, we try dividing 30,430,465 by 3:
30,430,465 ÷ 3 = 10,143,488.3333
If the quotient is a whole number, then 3 and 10,143,488.3333 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 | 30,430,465 | |
| -1 | -30,430,465 |
Let's try dividing by 4:
30,430,465 ÷ 4 = 7,607,616.25
If the quotient is a whole number, then 4 and 7,607,616.25 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 | 30,430,465 | |
| -1 | 30,430,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 37 | 65 | 185 | 481 | 2,405 | 12,653 | 63,265 | 164,489 | 468,161 | 822,445 | 2,340,805 | 6,086,093 | 30,430,465 |
| -1 | -5 | -13 | -37 | -65 | -185 | -481 | -2,405 | -12,653 | -63,265 | -164,489 | -468,161 | -822,445 | -2,340,805 | -6,086,093 | -30,430,465 |
