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 6,463,639, 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 | 6,463,639 | |
| -1 | -6,463,639 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,463,639.
Example:
1 x 6,463,639 = 6,463,639
and
-1 x -6,463,639 = 6,463,639
Notice both answers equal 6,463,639
With that explanation out of the way, let's continue. Next, we take the number 6,463,639 and divide it by 2:
6,463,639 ÷ 2 = 3,231,819.5
If the quotient is a whole number, then 2 and 3,231,819.5 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 | 6,463,639 | |
| -1 | -6,463,639 |
Now, we try dividing 6,463,639 by 3:
6,463,639 ÷ 3 = 2,154,546.3333
If the quotient is a whole number, then 3 and 2,154,546.3333 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 | 6,463,639 | |
| -1 | -6,463,639 |
Let's try dividing by 4:
6,463,639 ÷ 4 = 1,615,909.75
If the quotient is a whole number, then 4 and 1,615,909.75 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 | 6,463,639 | |
| -1 | 6,463,639 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 73 | 91 | 139 | 511 | 637 | 949 | 973 | 1,807 | 3,577 | 6,643 | 6,811 | 10,147 | 12,649 | 46,501 | 71,029 | 88,543 | 131,911 | 497,203 | 923,377 | 6,463,639 |
| -1 | -7 | -13 | -49 | -73 | -91 | -139 | -511 | -637 | -949 | -973 | -1,807 | -3,577 | -6,643 | -6,811 | -10,147 | -12,649 | -46,501 | -71,029 | -88,543 | -131,911 | -497,203 | -923,377 | -6,463,639 |
