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 345,356,011, 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 | 345,356,011 | |
| -1 | -345,356,011 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 345,356,011.
Example:
1 x 345,356,011 = 345,356,011
and
-1 x -345,356,011 = 345,356,011
Notice both answers equal 345,356,011
With that explanation out of the way, let's continue. Next, we take the number 345,356,011 and divide it by 2:
345,356,011 ÷ 2 = 172,678,005.5
If the quotient is a whole number, then 2 and 172,678,005.5 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 | 345,356,011 | |
| -1 | -345,356,011 |
Now, we try dividing 345,356,011 by 3:
345,356,011 ÷ 3 = 115,118,670.3333
If the quotient is a whole number, then 3 and 115,118,670.3333 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 | 345,356,011 | |
| -1 | -345,356,011 |
Let's try dividing by 4:
345,356,011 ÷ 4 = 86,339,002.75
If the quotient is a whole number, then 4 and 86,339,002.75 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 | 345,356,011 | |
| -1 | 345,356,011 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 143 | 1,001 | 345,011 | 2,415,077 | 3,795,121 | 4,485,143 | 26,565,847 | 31,396,001 | 49,336,573 | 345,356,011 |
| -1 | -7 | -11 | -13 | -77 | -91 | -143 | -1,001 | -345,011 | -2,415,077 | -3,795,121 | -4,485,143 | -26,565,847 | -31,396,001 | -49,336,573 | -345,356,011 |
