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 463,443,643, 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 | 463,443,643 | |
| -1 | -463,443,643 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 463,443,643.
Example:
1 x 463,443,643 = 463,443,643
and
-1 x -463,443,643 = 463,443,643
Notice both answers equal 463,443,643
With that explanation out of the way, let's continue. Next, we take the number 463,443,643 and divide it by 2:
463,443,643 ÷ 2 = 231,721,821.5
If the quotient is a whole number, then 2 and 231,721,821.5 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 | 463,443,643 | |
| -1 | -463,443,643 |
Now, we try dividing 463,443,643 by 3:
463,443,643 ÷ 3 = 154,481,214.3333
If the quotient is a whole number, then 3 and 154,481,214.3333 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 | 463,443,643 | |
| -1 | -463,443,643 |
Let's try dividing by 4:
463,443,643 ÷ 4 = 115,860,910.75
If the quotient is a whole number, then 4 and 115,860,910.75 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 | 463,443,643 | |
| -1 | 463,443,643 |
If you did it right, you will end up with this table:
| 1 | 13 | 59 | 107 | 767 | 1,391 | 5,647 | 6,313 | 73,411 | 82,069 | 333,173 | 604,229 | 4,331,249 | 7,854,977 | 35,649,511 | 463,443,643 |
| -1 | -13 | -59 | -107 | -767 | -1,391 | -5,647 | -6,313 | -73,411 | -82,069 | -333,173 | -604,229 | -4,331,249 | -7,854,977 | -35,649,511 | -463,443,643 |
