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 340,136,167, 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 | 340,136,167 | |
| -1 | -340,136,167 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 340,136,167.
Example:
1 x 340,136,167 = 340,136,167
and
-1 x -340,136,167 = 340,136,167
Notice both answers equal 340,136,167
With that explanation out of the way, let's continue. Next, we take the number 340,136,167 and divide it by 2:
340,136,167 ÷ 2 = 170,068,083.5
If the quotient is a whole number, then 2 and 170,068,083.5 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 | 340,136,167 | |
| -1 | -340,136,167 |
Now, we try dividing 340,136,167 by 3:
340,136,167 ÷ 3 = 113,378,722.3333
If the quotient is a whole number, then 3 and 113,378,722.3333 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 | 340,136,167 | |
| -1 | -340,136,167 |
Let's try dividing by 4:
340,136,167 ÷ 4 = 85,034,041.75
If the quotient is a whole number, then 4 and 85,034,041.75 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 | 340,136,167 | |
| -1 | 340,136,167 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 619 | 3,413 | 4,333 | 14,237 | 23,891 | 78,499 | 99,659 | 549,493 | 2,112,647 | 14,788,529 | 48,590,881 | 340,136,167 |
| -1 | -7 | -23 | -161 | -619 | -3,413 | -4,333 | -14,237 | -23,891 | -78,499 | -99,659 | -549,493 | -2,112,647 | -14,788,529 | -48,590,881 | -340,136,167 |
