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 34,798,915, 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 | 34,798,915 | |
| -1 | -34,798,915 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 34,798,915.
Example:
1 x 34,798,915 = 34,798,915
and
-1 x -34,798,915 = 34,798,915
Notice both answers equal 34,798,915
With that explanation out of the way, let's continue. Next, we take the number 34,798,915 and divide it by 2:
34,798,915 ÷ 2 = 17,399,457.5
If the quotient is a whole number, then 2 and 17,399,457.5 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 | 34,798,915 | |
| -1 | -34,798,915 |
Now, we try dividing 34,798,915 by 3:
34,798,915 ÷ 3 = 11,599,638.3333
If the quotient is a whole number, then 3 and 11,599,638.3333 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 | 34,798,915 | |
| -1 | -34,798,915 |
Let's try dividing by 4:
34,798,915 ÷ 4 = 8,699,728.75
If the quotient is a whole number, then 4 and 8,699,728.75 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 | 34,798,915 | |
| -1 | 34,798,915 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 113 | 565 | 1,921 | 3,623 | 9,605 | 18,115 | 61,591 | 307,955 | 409,399 | 2,046,995 | 6,959,783 | 34,798,915 |
| -1 | -5 | -17 | -85 | -113 | -565 | -1,921 | -3,623 | -9,605 | -18,115 | -61,591 | -307,955 | -409,399 | -2,046,995 | -6,959,783 | -34,798,915 |
