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 10,405,435, 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 | 10,405,435 | |
| -1 | -10,405,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,405,435.
Example:
1 x 10,405,435 = 10,405,435
and
-1 x -10,405,435 = 10,405,435
Notice both answers equal 10,405,435
With that explanation out of the way, let's continue. Next, we take the number 10,405,435 and divide it by 2:
10,405,435 ÷ 2 = 5,202,717.5
If the quotient is a whole number, then 2 and 5,202,717.5 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 | 10,405,435 | |
| -1 | -10,405,435 |
Now, we try dividing 10,405,435 by 3:
10,405,435 ÷ 3 = 3,468,478.3333
If the quotient is a whole number, then 3 and 3,468,478.3333 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 | 10,405,435 | |
| -1 | -10,405,435 |
Let's try dividing by 4:
10,405,435 ÷ 4 = 2,601,358.75
If the quotient is a whole number, then 4 and 2,601,358.75 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 | 10,405,435 | |
| -1 | 10,405,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 89 | 335 | 349 | 445 | 1,745 | 5,963 | 23,383 | 29,815 | 31,061 | 116,915 | 155,305 | 2,081,087 | 10,405,435 |
| -1 | -5 | -67 | -89 | -335 | -349 | -445 | -1,745 | -5,963 | -23,383 | -29,815 | -31,061 | -116,915 | -155,305 | -2,081,087 | -10,405,435 |
