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 356,377,255, 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 | 356,377,255 | |
| -1 | -356,377,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 356,377,255.
Example:
1 x 356,377,255 = 356,377,255
and
-1 x -356,377,255 = 356,377,255
Notice both answers equal 356,377,255
With that explanation out of the way, let's continue. Next, we take the number 356,377,255 and divide it by 2:
356,377,255 ÷ 2 = 178,188,627.5
If the quotient is a whole number, then 2 and 178,188,627.5 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 | 356,377,255 | |
| -1 | -356,377,255 |
Now, we try dividing 356,377,255 by 3:
356,377,255 ÷ 3 = 118,792,418.3333
If the quotient is a whole number, then 3 and 118,792,418.3333 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 | 356,377,255 | |
| -1 | -356,377,255 |
Let's try dividing by 4:
356,377,255 ÷ 4 = 89,094,313.75
If the quotient is a whole number, then 4 and 89,094,313.75 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 | 356,377,255 | |
| -1 | 356,377,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 373 | 1,865 | 4,849 | 14,699 | 24,245 | 73,495 | 191,087 | 955,435 | 5,482,727 | 27,413,635 | 71,275,451 | 356,377,255 |
| -1 | -5 | -13 | -65 | -373 | -1,865 | -4,849 | -14,699 | -24,245 | -73,495 | -191,087 | -955,435 | -5,482,727 | -27,413,635 | -71,275,451 | -356,377,255 |
