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 103,510,651, 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 | 103,510,651 | |
| -1 | -103,510,651 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,510,651.
Example:
1 x 103,510,651 = 103,510,651
and
-1 x -103,510,651 = 103,510,651
Notice both answers equal 103,510,651
With that explanation out of the way, let's continue. Next, we take the number 103,510,651 and divide it by 2:
103,510,651 ÷ 2 = 51,755,325.5
If the quotient is a whole number, then 2 and 51,755,325.5 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 | 103,510,651 | |
| -1 | -103,510,651 |
Now, we try dividing 103,510,651 by 3:
103,510,651 ÷ 3 = 34,503,550.3333
If the quotient is a whole number, then 3 and 34,503,550.3333 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 | 103,510,651 | |
| -1 | -103,510,651 |
Let's try dividing by 4:
103,510,651 ÷ 4 = 25,877,662.75
If the quotient is a whole number, then 4 and 25,877,662.75 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 | 103,510,651 | |
| -1 | 103,510,651 |
If you did it right, you will end up with this table:
| 1 | 19 | 109 | 151 | 331 | 2,071 | 2,869 | 6,289 | 16,459 | 36,079 | 49,981 | 312,721 | 685,501 | 949,639 | 5,447,929 | 103,510,651 |
| -1 | -19 | -109 | -151 | -331 | -2,071 | -2,869 | -6,289 | -16,459 | -36,079 | -49,981 | -312,721 | -685,501 | -949,639 | -5,447,929 | -103,510,651 |
