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 246,256,535, 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 | 246,256,535 | |
| -1 | -246,256,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 246,256,535.
Example:
1 x 246,256,535 = 246,256,535
and
-1 x -246,256,535 = 246,256,535
Notice both answers equal 246,256,535
With that explanation out of the way, let's continue. Next, we take the number 246,256,535 and divide it by 2:
246,256,535 ÷ 2 = 123,128,267.5
If the quotient is a whole number, then 2 and 123,128,267.5 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 | 246,256,535 | |
| -1 | -246,256,535 |
Now, we try dividing 246,256,535 by 3:
246,256,535 ÷ 3 = 82,085,511.6667
If the quotient is a whole number, then 3 and 82,085,511.6667 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 | 246,256,535 | |
| -1 | -246,256,535 |
Let's try dividing by 4:
246,256,535 ÷ 4 = 61,564,133.75
If the quotient is a whole number, then 4 and 61,564,133.75 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 | 246,256,535 | |
| -1 | 246,256,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 233 | 1,165 | 1,631 | 8,155 | 30,197 | 150,985 | 211,379 | 1,056,895 | 7,035,901 | 35,179,505 | 49,251,307 | 246,256,535 |
| -1 | -5 | -7 | -35 | -233 | -1,165 | -1,631 | -8,155 | -30,197 | -150,985 | -211,379 | -1,056,895 | -7,035,901 | -35,179,505 | -49,251,307 | -246,256,535 |
