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 246,406,435, 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 | 246,406,435 | |
| -1 | -246,406,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 246,406,435.
Example:
1 x 246,406,435 = 246,406,435
and
-1 x -246,406,435 = 246,406,435
Notice both answers equal 246,406,435
With that explanation out of the way, let's continue. Next, we take the number 246,406,435 and divide it by 2:
246,406,435 ÷ 2 = 123,203,217.5
If the quotient is a whole number, then 2 and 123,203,217.5 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 | 246,406,435 | |
| -1 | -246,406,435 |
Now, we try dividing 246,406,435 by 3:
246,406,435 ÷ 3 = 82,135,478.3333
If the quotient is a whole number, then 3 and 82,135,478.3333 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 | 246,406,435 | |
| -1 | -246,406,435 |
Let's try dividing by 4:
246,406,435 ÷ 4 = 61,601,608.75
If the quotient is a whole number, then 4 and 61,601,608.75 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 | 246,406,435 | |
| -1 | 246,406,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 347 | 1,735 | 3,817 | 12,911 | 19,085 | 64,555 | 142,021 | 710,105 | 4,480,117 | 22,400,585 | 49,281,287 | 246,406,435 |
| -1 | -5 | -11 | -55 | -347 | -1,735 | -3,817 | -12,911 | -19,085 | -64,555 | -142,021 | -710,105 | -4,480,117 | -22,400,585 | -49,281,287 | -246,406,435 |
