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 34,045,121, 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 | 34,045,121 | |
| -1 | -34,045,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 34,045,121.
Example:
1 x 34,045,121 = 34,045,121
and
-1 x -34,045,121 = 34,045,121
Notice both answers equal 34,045,121
With that explanation out of the way, let's continue. Next, we take the number 34,045,121 and divide it by 2:
34,045,121 ÷ 2 = 17,022,560.5
If the quotient is a whole number, then 2 and 17,022,560.5 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 | 34,045,121 | |
| -1 | -34,045,121 |
Now, we try dividing 34,045,121 by 3:
34,045,121 ÷ 3 = 11,348,373.6667
If the quotient is a whole number, then 3 and 11,348,373.6667 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 | 34,045,121 | |
| -1 | -34,045,121 |
Let's try dividing by 4:
34,045,121 ÷ 4 = 8,511,280.25
If the quotient is a whole number, then 4 and 8,511,280.25 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 | 34,045,121 | |
| -1 | 34,045,121 |
If you did it right, you will end up with this table:
| 1 | 11 | 43 | 167 | 431 | 473 | 1,837 | 4,741 | 7,181 | 18,533 | 71,977 | 78,991 | 203,863 | 791,747 | 3,095,011 | 34,045,121 |
| -1 | -11 | -43 | -167 | -431 | -473 | -1,837 | -4,741 | -7,181 | -18,533 | -71,977 | -78,991 | -203,863 | -791,747 | -3,095,011 | -34,045,121 |
