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 4,015,445, 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 | 4,015,445 | |
| -1 | -4,015,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,015,445.
Example:
1 x 4,015,445 = 4,015,445
and
-1 x -4,015,445 = 4,015,445
Notice both answers equal 4,015,445
With that explanation out of the way, let's continue. Next, we take the number 4,015,445 and divide it by 2:
4,015,445 ÷ 2 = 2,007,722.5
If the quotient is a whole number, then 2 and 2,007,722.5 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 | 4,015,445 | |
| -1 | -4,015,445 |
Now, we try dividing 4,015,445 by 3:
4,015,445 ÷ 3 = 1,338,481.6667
If the quotient is a whole number, then 3 and 1,338,481.6667 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 | 4,015,445 | |
| -1 | -4,015,445 |
Let's try dividing by 4:
4,015,445 ÷ 4 = 1,003,861.25
If the quotient is a whole number, then 4 and 1,003,861.25 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 | 4,015,445 | |
| -1 | 4,015,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 47 | 235 | 329 | 1,645 | 2,441 | 12,205 | 17,087 | 85,435 | 114,727 | 573,635 | 803,089 | 4,015,445 |
| -1 | -5 | -7 | -35 | -47 | -235 | -329 | -1,645 | -2,441 | -12,205 | -17,087 | -85,435 | -114,727 | -573,635 | -803,089 | -4,015,445 |
