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 7,654,405, 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 | 7,654,405 | |
| -1 | -7,654,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,654,405.
Example:
1 x 7,654,405 = 7,654,405
and
-1 x -7,654,405 = 7,654,405
Notice both answers equal 7,654,405
With that explanation out of the way, let's continue. Next, we take the number 7,654,405 and divide it by 2:
7,654,405 ÷ 2 = 3,827,202.5
If the quotient is a whole number, then 2 and 3,827,202.5 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 | 7,654,405 | |
| -1 | -7,654,405 |
Now, we try dividing 7,654,405 by 3:
7,654,405 ÷ 3 = 2,551,468.3333
If the quotient is a whole number, then 3 and 2,551,468.3333 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 | 7,654,405 | |
| -1 | -7,654,405 |
Let's try dividing by 4:
7,654,405 ÷ 4 = 1,913,601.25
If the quotient is a whole number, then 4 and 1,913,601.25 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 | 7,654,405 | |
| -1 | 7,654,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 145 | 319 | 1,595 | 4,799 | 23,995 | 52,789 | 139,171 | 263,945 | 695,855 | 1,530,881 | 7,654,405 |
| -1 | -5 | -11 | -29 | -55 | -145 | -319 | -1,595 | -4,799 | -23,995 | -52,789 | -139,171 | -263,945 | -695,855 | -1,530,881 | -7,654,405 |
