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 30,833,341, 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 | 30,833,341 | |
| -1 | -30,833,341 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,833,341.
Example:
1 x 30,833,341 = 30,833,341
and
-1 x -30,833,341 = 30,833,341
Notice both answers equal 30,833,341
With that explanation out of the way, let's continue. Next, we take the number 30,833,341 and divide it by 2:
30,833,341 ÷ 2 = 15,416,670.5
If the quotient is a whole number, then 2 and 15,416,670.5 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 | 30,833,341 | |
| -1 | -30,833,341 |
Now, we try dividing 30,833,341 by 3:
30,833,341 ÷ 3 = 10,277,780.3333
If the quotient is a whole number, then 3 and 10,277,780.3333 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 | 30,833,341 | |
| -1 | -30,833,341 |
Let's try dividing by 4:
30,833,341 ÷ 4 = 7,708,335.25
If the quotient is a whole number, then 4 and 7,708,335.25 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 | 30,833,341 | |
| -1 | 30,833,341 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 59 | 77 | 121 | 413 | 617 | 649 | 847 | 4,319 | 4,543 | 6,787 | 7,139 | 36,403 | 47,509 | 49,973 | 74,657 | 254,821 | 400,433 | 522,599 | 2,803,031 | 4,404,763 | 30,833,341 |
| -1 | -7 | -11 | -59 | -77 | -121 | -413 | -617 | -649 | -847 | -4,319 | -4,543 | -6,787 | -7,139 | -36,403 | -47,509 | -49,973 | -74,657 | -254,821 | -400,433 | -522,599 | -2,803,031 | -4,404,763 | -30,833,341 |
