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 30,562,625, 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 | 30,562,625 | |
| -1 | -30,562,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,562,625.
Example:
1 x 30,562,625 = 30,562,625
and
-1 x -30,562,625 = 30,562,625
Notice both answers equal 30,562,625
With that explanation out of the way, let's continue. Next, we take the number 30,562,625 and divide it by 2:
30,562,625 ÷ 2 = 15,281,312.5
If the quotient is a whole number, then 2 and 15,281,312.5 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 | 30,562,625 | |
| -1 | -30,562,625 |
Now, we try dividing 30,562,625 by 3:
30,562,625 ÷ 3 = 10,187,541.6667
If the quotient is a whole number, then 3 and 10,187,541.6667 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 | 30,562,625 | |
| -1 | -30,562,625 |
Let's try dividing by 4:
30,562,625 ÷ 4 = 7,640,656.25
If the quotient is a whole number, then 4 and 7,640,656.25 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 | 30,562,625 | |
| -1 | 30,562,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 139 | 695 | 1,759 | 3,475 | 8,795 | 17,375 | 43,975 | 219,875 | 244,501 | 1,222,505 | 6,112,525 | 30,562,625 |
| -1 | -5 | -25 | -125 | -139 | -695 | -1,759 | -3,475 | -8,795 | -17,375 | -43,975 | -219,875 | -244,501 | -1,222,505 | -6,112,525 | -30,562,625 |
