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 462,642,785, 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 | 462,642,785 | |
| -1 | -462,642,785 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 462,642,785.
Example:
1 x 462,642,785 = 462,642,785
and
-1 x -462,642,785 = 462,642,785
Notice both answers equal 462,642,785
With that explanation out of the way, let's continue. Next, we take the number 462,642,785 and divide it by 2:
462,642,785 ÷ 2 = 231,321,392.5
If the quotient is a whole number, then 2 and 231,321,392.5 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 | 462,642,785 | |
| -1 | -462,642,785 |
Now, we try dividing 462,642,785 by 3:
462,642,785 ÷ 3 = 154,214,261.6667
If the quotient is a whole number, then 3 and 154,214,261.6667 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 | 462,642,785 | |
| -1 | -462,642,785 |
Let's try dividing by 4:
462,642,785 ÷ 4 = 115,660,696.25
If the quotient is a whole number, then 4 and 115,660,696.25 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 | 462,642,785 | |
| -1 | 462,642,785 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 2,309 | 3,643 | 11,545 | 18,215 | 25,399 | 40,073 | 126,995 | 200,365 | 8,411,687 | 42,058,435 | 92,528,557 | 462,642,785 |
| -1 | -5 | -11 | -55 | -2,309 | -3,643 | -11,545 | -18,215 | -25,399 | -40,073 | -126,995 | -200,365 | -8,411,687 | -42,058,435 | -92,528,557 | -462,642,785 |
