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 102,550,235, 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 | 102,550,235 | |
| -1 | -102,550,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,550,235.
Example:
1 x 102,550,235 = 102,550,235
and
-1 x -102,550,235 = 102,550,235
Notice both answers equal 102,550,235
With that explanation out of the way, let's continue. Next, we take the number 102,550,235 and divide it by 2:
102,550,235 ÷ 2 = 51,275,117.5
If the quotient is a whole number, then 2 and 51,275,117.5 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 | 102,550,235 | |
| -1 | -102,550,235 |
Now, we try dividing 102,550,235 by 3:
102,550,235 ÷ 3 = 34,183,411.6667
If the quotient is a whole number, then 3 and 34,183,411.6667 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 | 102,550,235 | |
| -1 | -102,550,235 |
Let's try dividing by 4:
102,550,235 ÷ 4 = 25,637,558.75
If the quotient is a whole number, then 4 and 25,637,558.75 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 | 102,550,235 | |
| -1 | 102,550,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 83 | 145 | 415 | 2,407 | 8,521 | 12,035 | 42,605 | 247,109 | 707,243 | 1,235,545 | 3,536,215 | 20,510,047 | 102,550,235 |
| -1 | -5 | -29 | -83 | -145 | -415 | -2,407 | -8,521 | -12,035 | -42,605 | -247,109 | -707,243 | -1,235,545 | -3,536,215 | -20,510,047 | -102,550,235 |
