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 3,909,325, 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 | 3,909,325 | |
| -1 | -3,909,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,909,325.
Example:
1 x 3,909,325 = 3,909,325
and
-1 x -3,909,325 = 3,909,325
Notice both answers equal 3,909,325
With that explanation out of the way, let's continue. Next, we take the number 3,909,325 and divide it by 2:
3,909,325 ÷ 2 = 1,954,662.5
If the quotient is a whole number, then 2 and 1,954,662.5 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 | 3,909,325 | |
| -1 | -3,909,325 |
Now, we try dividing 3,909,325 by 3:
3,909,325 ÷ 3 = 1,303,108.3333
If the quotient is a whole number, then 3 and 1,303,108.3333 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 | 3,909,325 | |
| -1 | -3,909,325 |
Let's try dividing by 4:
3,909,325 ÷ 4 = 977,331.25
If the quotient is a whole number, then 4 and 977,331.25 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 | 3,909,325 | |
| -1 | 3,909,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 89 | 175 | 251 | 445 | 623 | 1,255 | 1,757 | 2,225 | 3,115 | 6,275 | 8,785 | 15,575 | 22,339 | 43,925 | 111,695 | 156,373 | 558,475 | 781,865 | 3,909,325 |
| -1 | -5 | -7 | -25 | -35 | -89 | -175 | -251 | -445 | -623 | -1,255 | -1,757 | -2,225 | -3,115 | -6,275 | -8,785 | -15,575 | -22,339 | -43,925 | -111,695 | -156,373 | -558,475 | -781,865 | -3,909,325 |
