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 65,343,583, 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 | 65,343,583 | |
| -1 | -65,343,583 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,343,583.
Example:
1 x 65,343,583 = 65,343,583
and
-1 x -65,343,583 = 65,343,583
Notice both answers equal 65,343,583
With that explanation out of the way, let's continue. Next, we take the number 65,343,583 and divide it by 2:
65,343,583 ÷ 2 = 32,671,791.5
If the quotient is a whole number, then 2 and 32,671,791.5 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 | 65,343,583 | |
| -1 | -65,343,583 |
Now, we try dividing 65,343,583 by 3:
65,343,583 ÷ 3 = 21,781,194.3333
If the quotient is a whole number, then 3 and 21,781,194.3333 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 | 65,343,583 | |
| -1 | -65,343,583 |
Let's try dividing by 4:
65,343,583 ÷ 4 = 16,335,895.75
If the quotient is a whole number, then 4 and 16,335,895.75 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 | 65,343,583 | |
| -1 | 65,343,583 |
If you did it right, you will end up with this table:
| 1 | 29 | 47 | 191 | 251 | 1,363 | 5,539 | 7,279 | 8,977 | 11,797 | 47,941 | 260,333 | 342,113 | 1,390,289 | 2,253,227 | 65,343,583 |
| -1 | -29 | -47 | -191 | -251 | -1,363 | -5,539 | -7,279 | -8,977 | -11,797 | -47,941 | -260,333 | -342,113 | -1,390,289 | -2,253,227 | -65,343,583 |
