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 30,153,529, 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 | 30,153,529 | |
| -1 | -30,153,529 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,153,529.
Example:
1 x 30,153,529 = 30,153,529
and
-1 x -30,153,529 = 30,153,529
Notice both answers equal 30,153,529
With that explanation out of the way, let's continue. Next, we take the number 30,153,529 and divide it by 2:
30,153,529 ÷ 2 = 15,076,764.5
If the quotient is a whole number, then 2 and 15,076,764.5 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 | 30,153,529 | |
| -1 | -30,153,529 |
Now, we try dividing 30,153,529 by 3:
30,153,529 ÷ 3 = 10,051,176.3333
If the quotient is a whole number, then 3 and 10,051,176.3333 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 | 30,153,529 | |
| -1 | -30,153,529 |
Let's try dividing by 4:
30,153,529 ÷ 4 = 7,538,382.25
If the quotient is a whole number, then 4 and 7,538,382.25 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 | 30,153,529 | |
| -1 | 30,153,529 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 23 | 119 | 161 | 391 | 479 | 529 | 2,737 | 3,353 | 3,703 | 8,143 | 8,993 | 11,017 | 57,001 | 62,951 | 77,119 | 187,289 | 253,391 | 1,311,023 | 1,773,737 | 4,307,647 | 30,153,529 |
| -1 | -7 | -17 | -23 | -119 | -161 | -391 | -479 | -529 | -2,737 | -3,353 | -3,703 | -8,143 | -8,993 | -11,017 | -57,001 | -62,951 | -77,119 | -187,289 | -253,391 | -1,311,023 | -1,773,737 | -4,307,647 | -30,153,529 |
