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 8,414,525, 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 | 8,414,525 | |
| -1 | -8,414,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,414,525.
Example:
1 x 8,414,525 = 8,414,525
and
-1 x -8,414,525 = 8,414,525
Notice both answers equal 8,414,525
With that explanation out of the way, let's continue. Next, we take the number 8,414,525 and divide it by 2:
8,414,525 ÷ 2 = 4,207,262.5
If the quotient is a whole number, then 2 and 4,207,262.5 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 | 8,414,525 | |
| -1 | -8,414,525 |
Now, we try dividing 8,414,525 by 3:
8,414,525 ÷ 3 = 2,804,841.6667
If the quotient is a whole number, then 3 and 2,804,841.6667 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 | 8,414,525 | |
| -1 | -8,414,525 |
Let's try dividing by 4:
8,414,525 ÷ 4 = 2,103,631.25
If the quotient is a whole number, then 4 and 2,103,631.25 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 | 8,414,525 | |
| -1 | 8,414,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 175 | 245 | 1,225 | 6,869 | 34,345 | 48,083 | 171,725 | 240,415 | 336,581 | 1,202,075 | 1,682,905 | 8,414,525 |
| -1 | -5 | -7 | -25 | -35 | -49 | -175 | -245 | -1,225 | -6,869 | -34,345 | -48,083 | -171,725 | -240,415 | -336,581 | -1,202,075 | -1,682,905 | -8,414,525 |
