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 102,051,005, 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 | 102,051,005 | |
| -1 | -102,051,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,051,005.
Example:
1 x 102,051,005 = 102,051,005
and
-1 x -102,051,005 = 102,051,005
Notice both answers equal 102,051,005
With that explanation out of the way, let's continue. Next, we take the number 102,051,005 and divide it by 2:
102,051,005 ÷ 2 = 51,025,502.5
If the quotient is a whole number, then 2 and 51,025,502.5 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 | 102,051,005 | |
| -1 | -102,051,005 |
Now, we try dividing 102,051,005 by 3:
102,051,005 ÷ 3 = 34,017,001.6667
If the quotient is a whole number, then 3 and 34,017,001.6667 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 | 102,051,005 | |
| -1 | -102,051,005 |
Let's try dividing by 4:
102,051,005 ÷ 4 = 25,512,751.25
If the quotient is a whole number, then 4 and 25,512,751.25 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 | 102,051,005 | |
| -1 | 102,051,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,669 | 1,747 | 8,345 | 8,735 | 11,683 | 12,229 | 58,415 | 61,145 | 2,915,743 | 14,578,715 | 20,410,201 | 102,051,005 |
| -1 | -5 | -7 | -35 | -1,669 | -1,747 | -8,345 | -8,735 | -11,683 | -12,229 | -58,415 | -61,145 | -2,915,743 | -14,578,715 | -20,410,201 | -102,051,005 |
