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 8,501,275, 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 | 8,501,275 | |
| -1 | -8,501,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,501,275.
Example:
1 x 8,501,275 = 8,501,275
and
-1 x -8,501,275 = 8,501,275
Notice both answers equal 8,501,275
With that explanation out of the way, let's continue. Next, we take the number 8,501,275 and divide it by 2:
8,501,275 ÷ 2 = 4,250,637.5
If the quotient is a whole number, then 2 and 4,250,637.5 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 | 8,501,275 | |
| -1 | -8,501,275 |
Now, we try dividing 8,501,275 by 3:
8,501,275 ÷ 3 = 2,833,758.3333
If the quotient is a whole number, then 3 and 2,833,758.3333 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 | 8,501,275 | |
| -1 | -8,501,275 |
Let's try dividing by 4:
8,501,275 ÷ 4 = 2,125,318.75
If the quotient is a whole number, then 4 and 2,125,318.75 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 | 8,501,275 | |
| -1 | 8,501,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 83 | 85 | 241 | 415 | 425 | 1,205 | 1,411 | 2,075 | 4,097 | 6,025 | 7,055 | 20,003 | 20,485 | 35,275 | 100,015 | 102,425 | 340,051 | 500,075 | 1,700,255 | 8,501,275 |
| -1 | -5 | -17 | -25 | -83 | -85 | -241 | -415 | -425 | -1,205 | -1,411 | -2,075 | -4,097 | -6,025 | -7,055 | -20,003 | -20,485 | -35,275 | -100,015 | -102,425 | -340,051 | -500,075 | -1,700,255 | -8,501,275 |
