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 7,405,535, 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 | 7,405,535 | |
| -1 | -7,405,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,405,535.
Example:
1 x 7,405,535 = 7,405,535
and
-1 x -7,405,535 = 7,405,535
Notice both answers equal 7,405,535
With that explanation out of the way, let's continue. Next, we take the number 7,405,535 and divide it by 2:
7,405,535 ÷ 2 = 3,702,767.5
If the quotient is a whole number, then 2 and 3,702,767.5 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 | 7,405,535 | |
| -1 | -7,405,535 |
Now, we try dividing 7,405,535 by 3:
7,405,535 ÷ 3 = 2,468,511.6667
If the quotient is a whole number, then 3 and 2,468,511.6667 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 | 7,405,535 | |
| -1 | -7,405,535 |
Let's try dividing by 4:
7,405,535 ÷ 4 = 1,851,383.75
If the quotient is a whole number, then 4 and 1,851,383.75 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 | 7,405,535 | |
| -1 | 7,405,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 137 | 569 | 685 | 2,603 | 2,845 | 10,811 | 13,015 | 54,055 | 77,953 | 389,765 | 1,481,107 | 7,405,535 |
| -1 | -5 | -19 | -95 | -137 | -569 | -685 | -2,603 | -2,845 | -10,811 | -13,015 | -54,055 | -77,953 | -389,765 | -1,481,107 | -7,405,535 |
