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 62,892,109, 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 | 62,892,109 | |
| -1 | -62,892,109 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,892,109.
Example:
1 x 62,892,109 = 62,892,109
and
-1 x -62,892,109 = 62,892,109
Notice both answers equal 62,892,109
With that explanation out of the way, let's continue. Next, we take the number 62,892,109 and divide it by 2:
62,892,109 ÷ 2 = 31,446,054.5
If the quotient is a whole number, then 2 and 31,446,054.5 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 | 62,892,109 | |
| -1 | -62,892,109 |
Now, we try dividing 62,892,109 by 3:
62,892,109 ÷ 3 = 20,964,036.3333
If the quotient is a whole number, then 3 and 20,964,036.3333 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 | 62,892,109 | |
| -1 | -62,892,109 |
Let's try dividing by 4:
62,892,109 ÷ 4 = 15,723,027.25
If the quotient is a whole number, then 4 and 15,723,027.25 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 | 62,892,109 | |
| -1 | 62,892,109 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 103 | 133 | 721 | 1,957 | 4,591 | 13,699 | 32,137 | 87,229 | 472,873 | 610,603 | 3,310,111 | 8,984,587 | 62,892,109 |
| -1 | -7 | -19 | -103 | -133 | -721 | -1,957 | -4,591 | -13,699 | -32,137 | -87,229 | -472,873 | -610,603 | -3,310,111 | -8,984,587 | -62,892,109 |
