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 355,622,155, 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 | 355,622,155 | |
| -1 | -355,622,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 355,622,155.
Example:
1 x 355,622,155 = 355,622,155
and
-1 x -355,622,155 = 355,622,155
Notice both answers equal 355,622,155
With that explanation out of the way, let's continue. Next, we take the number 355,622,155 and divide it by 2:
355,622,155 ÷ 2 = 177,811,077.5
If the quotient is a whole number, then 2 and 177,811,077.5 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 | 355,622,155 | |
| -1 | -355,622,155 |
Now, we try dividing 355,622,155 by 3:
355,622,155 ÷ 3 = 118,540,718.3333
If the quotient is a whole number, then 3 and 118,540,718.3333 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 | 355,622,155 | |
| -1 | -355,622,155 |
Let's try dividing by 4:
355,622,155 ÷ 4 = 88,905,538.75
If the quotient is a whole number, then 4 and 88,905,538.75 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 | 355,622,155 | |
| -1 | 355,622,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 569 | 2,551 | 2,845 | 3,983 | 12,755 | 17,857 | 19,915 | 27,881 | 89,285 | 124,999 | 139,405 | 624,995 | 1,451,519 | 7,257,595 | 10,160,633 | 50,803,165 | 71,124,431 | 355,622,155 |
| -1 | -5 | -7 | -35 | -49 | -245 | -569 | -2,551 | -2,845 | -3,983 | -12,755 | -17,857 | -19,915 | -27,881 | -89,285 | -124,999 | -139,405 | -624,995 | -1,451,519 | -7,257,595 | -10,160,633 | -50,803,165 | -71,124,431 | -355,622,155 |
