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 34,020,715, 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 | 34,020,715 | |
| -1 | -34,020,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 34,020,715.
Example:
1 x 34,020,715 = 34,020,715
and
-1 x -34,020,715 = 34,020,715
Notice both answers equal 34,020,715
With that explanation out of the way, let's continue. Next, we take the number 34,020,715 and divide it by 2:
34,020,715 ÷ 2 = 17,010,357.5
If the quotient is a whole number, then 2 and 17,010,357.5 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 | 34,020,715 | |
| -1 | -34,020,715 |
Now, we try dividing 34,020,715 by 3:
34,020,715 ÷ 3 = 11,340,238.3333
If the quotient is a whole number, then 3 and 11,340,238.3333 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 | 34,020,715 | |
| -1 | -34,020,715 |
Let's try dividing by 4:
34,020,715 ÷ 4 = 8,505,178.75
If the quotient is a whole number, then 4 and 8,505,178.75 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 | 34,020,715 | |
| -1 | 34,020,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 71 | 235 | 355 | 2,039 | 3,337 | 10,195 | 16,685 | 95,833 | 144,769 | 479,165 | 723,845 | 6,804,143 | 34,020,715 |
| -1 | -5 | -47 | -71 | -235 | -355 | -2,039 | -3,337 | -10,195 | -16,685 | -95,833 | -144,769 | -479,165 | -723,845 | -6,804,143 | -34,020,715 |
