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 8,474,765, 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 | 8,474,765 | |
| -1 | -8,474,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,474,765.
Example:
1 x 8,474,765 = 8,474,765
and
-1 x -8,474,765 = 8,474,765
Notice both answers equal 8,474,765
With that explanation out of the way, let's continue. Next, we take the number 8,474,765 and divide it by 2:
8,474,765 ÷ 2 = 4,237,382.5
If the quotient is a whole number, then 2 and 4,237,382.5 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 | 8,474,765 | |
| -1 | -8,474,765 |
Now, we try dividing 8,474,765 by 3:
8,474,765 ÷ 3 = 2,824,921.6667
If the quotient is a whole number, then 3 and 2,824,921.6667 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 | 8,474,765 | |
| -1 | -8,474,765 |
Let's try dividing by 4:
8,474,765 ÷ 4 = 2,118,691.25
If the quotient is a whole number, then 4 and 2,118,691.25 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 | 8,474,765 | |
| -1 | 8,474,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 241 | 541 | 1,205 | 2,705 | 3,133 | 7,033 | 15,665 | 35,165 | 130,381 | 651,905 | 1,694,953 | 8,474,765 |
| -1 | -5 | -13 | -65 | -241 | -541 | -1,205 | -2,705 | -3,133 | -7,033 | -15,665 | -35,165 | -130,381 | -651,905 | -1,694,953 | -8,474,765 |
