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 30,410,545, 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 | 30,410,545 | |
| -1 | -30,410,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,410,545.
Example:
1 x 30,410,545 = 30,410,545
and
-1 x -30,410,545 = 30,410,545
Notice both answers equal 30,410,545
With that explanation out of the way, let's continue. Next, we take the number 30,410,545 and divide it by 2:
30,410,545 ÷ 2 = 15,205,272.5
If the quotient is a whole number, then 2 and 15,205,272.5 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 | 30,410,545 | |
| -1 | -30,410,545 |
Now, we try dividing 30,410,545 by 3:
30,410,545 ÷ 3 = 10,136,848.3333
If the quotient is a whole number, then 3 and 10,136,848.3333 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 | 30,410,545 | |
| -1 | -30,410,545 |
Let's try dividing by 4:
30,410,545 ÷ 4 = 7,602,636.25
If the quotient is a whole number, then 4 and 7,602,636.25 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 | 30,410,545 | |
| -1 | 30,410,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 19 | 55 | 95 | 209 | 1,045 | 29,101 | 145,505 | 320,111 | 552,919 | 1,600,555 | 2,764,595 | 6,082,109 | 30,410,545 |
| -1 | -5 | -11 | -19 | -55 | -95 | -209 | -1,045 | -29,101 | -145,505 | -320,111 | -552,919 | -1,600,555 | -2,764,595 | -6,082,109 | -30,410,545 |
