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 336,280,385, 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 | 336,280,385 | |
| -1 | -336,280,385 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 336,280,385.
Example:
1 x 336,280,385 = 336,280,385
and
-1 x -336,280,385 = 336,280,385
Notice both answers equal 336,280,385
With that explanation out of the way, let's continue. Next, we take the number 336,280,385 and divide it by 2:
336,280,385 ÷ 2 = 168,140,192.5
If the quotient is a whole number, then 2 and 168,140,192.5 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 | 336,280,385 | |
| -1 | -336,280,385 |
Now, we try dividing 336,280,385 by 3:
336,280,385 ÷ 3 = 112,093,461.6667
If the quotient is a whole number, then 3 and 112,093,461.6667 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 | 336,280,385 | |
| -1 | -336,280,385 |
Let's try dividing by 4:
336,280,385 ÷ 4 = 84,070,096.25
If the quotient is a whole number, then 4 and 84,070,096.25 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 | 336,280,385 | |
| -1 | 336,280,385 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 167 | 245 | 835 | 1,169 | 5,845 | 8,183 | 8,219 | 40,915 | 41,095 | 57,533 | 287,665 | 402,731 | 1,372,573 | 2,013,655 | 6,862,865 | 9,608,011 | 48,040,055 | 67,256,077 | 336,280,385 |
| -1 | -5 | -7 | -35 | -49 | -167 | -245 | -835 | -1,169 | -5,845 | -8,183 | -8,219 | -40,915 | -41,095 | -57,533 | -287,665 | -402,731 | -1,372,573 | -2,013,655 | -6,862,865 | -9,608,011 | -48,040,055 | -67,256,077 | -336,280,385 |
