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 100,285,075, 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 | 100,285,075 | |
| -1 | -100,285,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,285,075.
Example:
1 x 100,285,075 = 100,285,075
and
-1 x -100,285,075 = 100,285,075
Notice both answers equal 100,285,075
With that explanation out of the way, let's continue. Next, we take the number 100,285,075 and divide it by 2:
100,285,075 ÷ 2 = 50,142,537.5
If the quotient is a whole number, then 2 and 50,142,537.5 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 | 100,285,075 | |
| -1 | -100,285,075 |
Now, we try dividing 100,285,075 by 3:
100,285,075 ÷ 3 = 33,428,358.3333
If the quotient is a whole number, then 3 and 33,428,358.3333 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 | 100,285,075 | |
| -1 | -100,285,075 |
Let's try dividing by 4:
100,285,075 ÷ 4 = 25,071,268.75
If the quotient is a whole number, then 4 and 25,071,268.75 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 | 100,285,075 | |
| -1 | 100,285,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 47 | 55 | 235 | 275 | 517 | 1,175 | 2,585 | 7,759 | 12,925 | 38,795 | 85,349 | 193,975 | 364,673 | 426,745 | 1,823,365 | 2,133,725 | 4,011,403 | 9,116,825 | 20,057,015 | 100,285,075 |
| -1 | -5 | -11 | -25 | -47 | -55 | -235 | -275 | -517 | -1,175 | -2,585 | -7,759 | -12,925 | -38,795 | -85,349 | -193,975 | -364,673 | -426,745 | -1,823,365 | -2,133,725 | -4,011,403 | -9,116,825 | -20,057,015 | -100,285,075 |
