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 100,150,715, 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 | 100,150,715 | |
| -1 | -100,150,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,150,715.
Example:
1 x 100,150,715 = 100,150,715
and
-1 x -100,150,715 = 100,150,715
Notice both answers equal 100,150,715
With that explanation out of the way, let's continue. Next, we take the number 100,150,715 and divide it by 2:
100,150,715 ÷ 2 = 50,075,357.5
If the quotient is a whole number, then 2 and 50,075,357.5 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 | 100,150,715 | |
| -1 | -100,150,715 |
Now, we try dividing 100,150,715 by 3:
100,150,715 ÷ 3 = 33,383,571.6667
If the quotient is a whole number, then 3 and 33,383,571.6667 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 | 100,150,715 | |
| -1 | -100,150,715 |
Let's try dividing by 4:
100,150,715 ÷ 4 = 25,037,678.75
If the quotient is a whole number, then 4 and 25,037,678.75 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 | 100,150,715 | |
| -1 | 100,150,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 61 | 305 | 427 | 769 | 2,135 | 3,721 | 3,845 | 5,383 | 18,605 | 26,047 | 26,915 | 46,909 | 130,235 | 234,545 | 328,363 | 1,641,815 | 2,861,449 | 14,307,245 | 20,030,143 | 100,150,715 |
| -1 | -5 | -7 | -35 | -61 | -305 | -427 | -769 | -2,135 | -3,721 | -3,845 | -5,383 | -18,605 | -26,047 | -26,915 | -46,909 | -130,235 | -234,545 | -328,363 | -1,641,815 | -2,861,449 | -14,307,245 | -20,030,143 | -100,150,715 |
