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 102,101,615, 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 | 102,101,615 | |
| -1 | -102,101,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,101,615.
Example:
1 x 102,101,615 = 102,101,615
and
-1 x -102,101,615 = 102,101,615
Notice both answers equal 102,101,615
With that explanation out of the way, let's continue. Next, we take the number 102,101,615 and divide it by 2:
102,101,615 ÷ 2 = 51,050,807.5
If the quotient is a whole number, then 2 and 51,050,807.5 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 | 102,101,615 | |
| -1 | -102,101,615 |
Now, we try dividing 102,101,615 by 3:
102,101,615 ÷ 3 = 34,033,871.6667
If the quotient is a whole number, then 3 and 34,033,871.6667 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 | 102,101,615 | |
| -1 | -102,101,615 |
Let's try dividing by 4:
102,101,615 ÷ 4 = 25,525,403.75
If the quotient is a whole number, then 4 and 25,525,403.75 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 | 102,101,615 | |
| -1 | 102,101,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 121 | 385 | 605 | 847 | 4,235 | 24,109 | 120,545 | 168,763 | 265,199 | 843,815 | 1,325,995 | 1,856,393 | 2,917,189 | 9,281,965 | 14,585,945 | 20,420,323 | 102,101,615 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -121 | -385 | -605 | -847 | -4,235 | -24,109 | -120,545 | -168,763 | -265,199 | -843,815 | -1,325,995 | -1,856,393 | -2,917,189 | -9,281,965 | -14,585,945 | -20,420,323 | -102,101,615 |
