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 34,874,791, 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 | 34,874,791 | |
| -1 | -34,874,791 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 34,874,791.
Example:
1 x 34,874,791 = 34,874,791
and
-1 x -34,874,791 = 34,874,791
Notice both answers equal 34,874,791
With that explanation out of the way, let's continue. Next, we take the number 34,874,791 and divide it by 2:
34,874,791 ÷ 2 = 17,437,395.5
If the quotient is a whole number, then 2 and 17,437,395.5 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 | 34,874,791 | |
| -1 | -34,874,791 |
Now, we try dividing 34,874,791 by 3:
34,874,791 ÷ 3 = 11,624,930.3333
If the quotient is a whole number, then 3 and 11,624,930.3333 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 | 34,874,791 | |
| -1 | -34,874,791 |
Let's try dividing by 4:
34,874,791 ÷ 4 = 8,718,697.75
If the quotient is a whole number, then 4 and 8,718,697.75 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 | 34,874,791 | |
| -1 | 34,874,791 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 149 | 203 | 1,043 | 1,153 | 4,321 | 8,071 | 30,247 | 33,437 | 171,797 | 234,059 | 1,202,579 | 4,982,113 | 34,874,791 |
| -1 | -7 | -29 | -149 | -203 | -1,043 | -1,153 | -4,321 | -8,071 | -30,247 | -33,437 | -171,797 | -234,059 | -1,202,579 | -4,982,113 | -34,874,791 |
