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 65,404,643, 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 | 65,404,643 | |
| -1 | -65,404,643 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,404,643.
Example:
1 x 65,404,643 = 65,404,643
and
-1 x -65,404,643 = 65,404,643
Notice both answers equal 65,404,643
With that explanation out of the way, let's continue. Next, we take the number 65,404,643 and divide it by 2:
65,404,643 ÷ 2 = 32,702,321.5
If the quotient is a whole number, then 2 and 32,702,321.5 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 | 65,404,643 | |
| -1 | -65,404,643 |
Now, we try dividing 65,404,643 by 3:
65,404,643 ÷ 3 = 21,801,547.6667
If the quotient is a whole number, then 3 and 21,801,547.6667 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 | 65,404,643 | |
| -1 | -65,404,643 |
Let's try dividing by 4:
65,404,643 ÷ 4 = 16,351,160.75
If the quotient is a whole number, then 4 and 16,351,160.75 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 | 65,404,643 | |
| -1 | 65,404,643 |
If you did it right, you will end up with this table:
| 1 | 139 | 419 | 1,123 | 58,241 | 156,097 | 470,537 | 65,404,643 |
| -1 | -139 | -419 | -1,123 | -58,241 | -156,097 | -470,537 | -65,404,643 |
