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 8,418,425, 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 | 8,418,425 | |
| -1 | -8,418,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,418,425.
Example:
1 x 8,418,425 = 8,418,425
and
-1 x -8,418,425 = 8,418,425
Notice both answers equal 8,418,425
With that explanation out of the way, let's continue. Next, we take the number 8,418,425 and divide it by 2:
8,418,425 ÷ 2 = 4,209,212.5
If the quotient is a whole number, then 2 and 4,209,212.5 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 | 8,418,425 | |
| -1 | -8,418,425 |
Now, we try dividing 8,418,425 by 3:
8,418,425 ÷ 3 = 2,806,141.6667
If the quotient is a whole number, then 3 and 2,806,141.6667 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 | 8,418,425 | |
| -1 | -8,418,425 |
Let's try dividing by 4:
8,418,425 ÷ 4 = 2,104,606.25
If the quotient is a whole number, then 4 and 2,104,606.25 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 | 8,418,425 | |
| -1 | 8,418,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 37 | 95 | 185 | 475 | 479 | 703 | 925 | 2,395 | 3,515 | 9,101 | 11,975 | 17,575 | 17,723 | 45,505 | 88,615 | 227,525 | 336,737 | 443,075 | 1,683,685 | 8,418,425 |
| -1 | -5 | -19 | -25 | -37 | -95 | -185 | -475 | -479 | -703 | -925 | -2,395 | -3,515 | -9,101 | -11,975 | -17,575 | -17,723 | -45,505 | -88,615 | -227,525 | -336,737 | -443,075 | -1,683,685 | -8,418,425 |
