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 8,990,975, 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 | 8,990,975 | |
| -1 | -8,990,975 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,990,975.
Example:
1 x 8,990,975 = 8,990,975
and
-1 x -8,990,975 = 8,990,975
Notice both answers equal 8,990,975
With that explanation out of the way, let's continue. Next, we take the number 8,990,975 and divide it by 2:
8,990,975 ÷ 2 = 4,495,487.5
If the quotient is a whole number, then 2 and 4,495,487.5 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 | 8,990,975 | |
| -1 | -8,990,975 |
Now, we try dividing 8,990,975 by 3:
8,990,975 ÷ 3 = 2,996,991.6667
If the quotient is a whole number, then 3 and 2,996,991.6667 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 | 8,990,975 | |
| -1 | -8,990,975 |
Let's try dividing by 4:
8,990,975 ÷ 4 = 2,247,743.75
If the quotient is a whole number, then 4 and 2,247,743.75 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 | 8,990,975 | |
| -1 | 8,990,975 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 83 | 175 | 415 | 581 | 619 | 2,075 | 2,905 | 3,095 | 4,333 | 14,525 | 15,475 | 21,665 | 51,377 | 108,325 | 256,885 | 359,639 | 1,284,425 | 1,798,195 | 8,990,975 |
| -1 | -5 | -7 | -25 | -35 | -83 | -175 | -415 | -581 | -619 | -2,075 | -2,905 | -3,095 | -4,333 | -14,525 | -15,475 | -21,665 | -51,377 | -108,325 | -256,885 | -359,639 | -1,284,425 | -1,798,195 | -8,990,975 |
