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 30,034,543, 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 | 30,034,543 | |
| -1 | -30,034,543 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,034,543.
Example:
1 x 30,034,543 = 30,034,543
and
-1 x -30,034,543 = 30,034,543
Notice both answers equal 30,034,543
With that explanation out of the way, let's continue. Next, we take the number 30,034,543 and divide it by 2:
30,034,543 ÷ 2 = 15,017,271.5
If the quotient is a whole number, then 2 and 15,017,271.5 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 | 30,034,543 | |
| -1 | -30,034,543 |
Now, we try dividing 30,034,543 by 3:
30,034,543 ÷ 3 = 10,011,514.3333
If the quotient is a whole number, then 3 and 10,011,514.3333 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 | 30,034,543 | |
| -1 | -30,034,543 |
Let's try dividing by 4:
30,034,543 ÷ 4 = 7,508,635.75
If the quotient is a whole number, then 4 and 7,508,635.75 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 | 30,034,543 | |
| -1 | 30,034,543 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 163 | 1,141 | 1,793 | 2,393 | 12,551 | 16,751 | 26,323 | 184,261 | 390,059 | 2,730,413 | 4,290,649 | 30,034,543 |
| -1 | -7 | -11 | -77 | -163 | -1,141 | -1,793 | -2,393 | -12,551 | -16,751 | -26,323 | -184,261 | -390,059 | -2,730,413 | -4,290,649 | -30,034,543 |
