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 340,405,351, 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 | 340,405,351 | |
| -1 | -340,405,351 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 340,405,351.
Example:
1 x 340,405,351 = 340,405,351
and
-1 x -340,405,351 = 340,405,351
Notice both answers equal 340,405,351
With that explanation out of the way, let's continue. Next, we take the number 340,405,351 and divide it by 2:
340,405,351 ÷ 2 = 170,202,675.5
If the quotient is a whole number, then 2 and 170,202,675.5 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 | 340,405,351 | |
| -1 | -340,405,351 |
Now, we try dividing 340,405,351 by 3:
340,405,351 ÷ 3 = 113,468,450.3333
If the quotient is a whole number, then 3 and 113,468,450.3333 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 | 340,405,351 | |
| -1 | -340,405,351 |
Let's try dividing by 4:
340,405,351 ÷ 4 = 85,101,337.75
If the quotient is a whole number, then 4 and 85,101,337.75 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 | 340,405,351 | |
| -1 | 340,405,351 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 73 | 143 | 803 | 949 | 10,439 | 32,609 | 358,699 | 423,917 | 2,380,457 | 4,663,087 | 26,185,027 | 30,945,941 | 340,405,351 |
| -1 | -11 | -13 | -73 | -143 | -803 | -949 | -10,439 | -32,609 | -358,699 | -423,917 | -2,380,457 | -4,663,087 | -26,185,027 | -30,945,941 | -340,405,351 |
