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 30,526,555, 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 | 30,526,555 | |
| -1 | -30,526,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,526,555.
Example:
1 x 30,526,555 = 30,526,555
and
-1 x -30,526,555 = 30,526,555
Notice both answers equal 30,526,555
With that explanation out of the way, let's continue. Next, we take the number 30,526,555 and divide it by 2:
30,526,555 ÷ 2 = 15,263,277.5
If the quotient is a whole number, then 2 and 15,263,277.5 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 | 30,526,555 | |
| -1 | -30,526,555 |
Now, we try dividing 30,526,555 by 3:
30,526,555 ÷ 3 = 10,175,518.3333
If the quotient is a whole number, then 3 and 10,175,518.3333 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 | 30,526,555 | |
| -1 | -30,526,555 |
Let's try dividing by 4:
30,526,555 ÷ 4 = 7,631,638.75
If the quotient is a whole number, then 4 and 7,631,638.75 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 | 30,526,555 | |
| -1 | 30,526,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 89 | 181 | 379 | 445 | 905 | 1,895 | 16,109 | 33,731 | 68,599 | 80,545 | 168,655 | 342,995 | 6,105,311 | 30,526,555 |
| -1 | -5 | -89 | -181 | -379 | -445 | -905 | -1,895 | -16,109 | -33,731 | -68,599 | -80,545 | -168,655 | -342,995 | -6,105,311 | -30,526,555 |
