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 8,869,007, 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 | 8,869,007 | |
| -1 | -8,869,007 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,869,007.
Example:
1 x 8,869,007 = 8,869,007
and
-1 x -8,869,007 = 8,869,007
Notice both answers equal 8,869,007
With that explanation out of the way, let's continue. Next, we take the number 8,869,007 and divide it by 2:
8,869,007 ÷ 2 = 4,434,503.5
If the quotient is a whole number, then 2 and 4,434,503.5 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 | 8,869,007 | |
| -1 | -8,869,007 |
Now, we try dividing 8,869,007 by 3:
8,869,007 ÷ 3 = 2,956,335.6667
If the quotient is a whole number, then 3 and 2,956,335.6667 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 | 8,869,007 | |
| -1 | -8,869,007 |
Let's try dividing by 4:
8,869,007 ÷ 4 = 2,217,251.75
If the quotient is a whole number, then 4 and 2,217,251.75 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 | 8,869,007 | |
| -1 | 8,869,007 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 31 | 161 | 217 | 713 | 1,777 | 4,991 | 12,439 | 40,871 | 55,087 | 286,097 | 385,609 | 1,267,001 | 8,869,007 |
| -1 | -7 | -23 | -31 | -161 | -217 | -713 | -1,777 | -4,991 | -12,439 | -40,871 | -55,087 | -286,097 | -385,609 | -1,267,001 | -8,869,007 |
