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 6,470,605, 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 | 6,470,605 | |
-1 | -6,470,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,470,605.
Example:
1 x 6,470,605 = 6,470,605
and
-1 x -6,470,605 = 6,470,605
Notice both answers equal 6,470,605
With that explanation out of the way, let's continue. Next, we take the number 6,470,605 and divide it by 2:
6,470,605 ÷ 2 = 3,235,302.5
If the quotient is a whole number, then 2 and 3,235,302.5 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 | 6,470,605 | |
-1 | -6,470,605 |
Now, we try dividing 6,470,605 by 3:
6,470,605 ÷ 3 = 2,156,868.3333
If the quotient is a whole number, then 3 and 2,156,868.3333 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 | 6,470,605 | |
-1 | -6,470,605 |
Let's try dividing by 4:
6,470,605 ÷ 4 = 1,617,651.25
If the quotient is a whole number, then 4 and 1,617,651.25 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 | 6,470,605 | |
-1 | 6,470,605 |
If you did it right, you will end up with this table:
1 | 5 | 1,294,121 | 6,470,605 |
-1 | -5 | -1,294,121 | -6,470,605 |
