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 62,163,509, 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 | 62,163,509 | |
| -1 | -62,163,509 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,163,509.
Example:
1 x 62,163,509 = 62,163,509
and
-1 x -62,163,509 = 62,163,509
Notice both answers equal 62,163,509
With that explanation out of the way, let's continue. Next, we take the number 62,163,509 and divide it by 2:
62,163,509 ÷ 2 = 31,081,754.5
If the quotient is a whole number, then 2 and 31,081,754.5 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 | 62,163,509 | |
| -1 | -62,163,509 |
Now, we try dividing 62,163,509 by 3:
62,163,509 ÷ 3 = 20,721,169.6667
If the quotient is a whole number, then 3 and 20,721,169.6667 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 | 62,163,509 | |
| -1 | -62,163,509 |
Let's try dividing by 4:
62,163,509 ÷ 4 = 15,540,877.25
If the quotient is a whole number, then 4 and 15,540,877.25 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 | 62,163,509 | |
| -1 | 62,163,509 |
If you did it right, you will end up with this table:
| 1 | 17 | 43 | 277 | 307 | 731 | 4,709 | 5,219 | 11,911 | 13,201 | 85,039 | 202,487 | 224,417 | 1,445,663 | 3,656,677 | 62,163,509 |
| -1 | -17 | -43 | -277 | -307 | -731 | -4,709 | -5,219 | -11,911 | -13,201 | -85,039 | -202,487 | -224,417 | -1,445,663 | -3,656,677 | -62,163,509 |
