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 102,111,295, 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 | 102,111,295 | |
| -1 | -102,111,295 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,111,295.
Example:
1 x 102,111,295 = 102,111,295
and
-1 x -102,111,295 = 102,111,295
Notice both answers equal 102,111,295
With that explanation out of the way, let's continue. Next, we take the number 102,111,295 and divide it by 2:
102,111,295 ÷ 2 = 51,055,647.5
If the quotient is a whole number, then 2 and 51,055,647.5 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 | 102,111,295 | |
| -1 | -102,111,295 |
Now, we try dividing 102,111,295 by 3:
102,111,295 ÷ 3 = 34,037,098.3333
If the quotient is a whole number, then 3 and 34,037,098.3333 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 | 102,111,295 | |
| -1 | -102,111,295 |
Let's try dividing by 4:
102,111,295 ÷ 4 = 25,527,823.75
If the quotient is a whole number, then 4 and 25,527,823.75 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 | 102,111,295 | |
| -1 | 102,111,295 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 121 | 143 | 605 | 715 | 1,573 | 7,865 | 12,983 | 64,915 | 142,813 | 168,779 | 714,065 | 843,895 | 1,570,943 | 1,856,569 | 7,854,715 | 9,282,845 | 20,422,259 | 102,111,295 |
| -1 | -5 | -11 | -13 | -55 | -65 | -121 | -143 | -605 | -715 | -1,573 | -7,865 | -12,983 | -64,915 | -142,813 | -168,779 | -714,065 | -843,895 | -1,570,943 | -1,856,569 | -7,854,715 | -9,282,845 | -20,422,259 | -102,111,295 |
