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 371,322,245, 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 | 371,322,245 | |
| -1 | -371,322,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 371,322,245.
Example:
1 x 371,322,245 = 371,322,245
and
-1 x -371,322,245 = 371,322,245
Notice both answers equal 371,322,245
With that explanation out of the way, let's continue. Next, we take the number 371,322,245 and divide it by 2:
371,322,245 ÷ 2 = 185,661,122.5
If the quotient is a whole number, then 2 and 185,661,122.5 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 | 371,322,245 | |
| -1 | -371,322,245 |
Now, we try dividing 371,322,245 by 3:
371,322,245 ÷ 3 = 123,774,081.6667
If the quotient is a whole number, then 3 and 123,774,081.6667 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 | 371,322,245 | |
| -1 | -371,322,245 |
Let's try dividing by 4:
371,322,245 ÷ 4 = 92,830,561.25
If the quotient is a whole number, then 4 and 92,830,561.25 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 | 371,322,245 | |
| -1 | 371,322,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 49 | 85 | 119 | 245 | 595 | 833 | 4,165 | 89,153 | 445,765 | 624,071 | 1,515,601 | 3,120,355 | 4,368,497 | 7,578,005 | 10,609,207 | 21,842,485 | 53,046,035 | 74,264,449 | 371,322,245 |
| -1 | -5 | -7 | -17 | -35 | -49 | -85 | -119 | -245 | -595 | -833 | -4,165 | -89,153 | -445,765 | -624,071 | -1,515,601 | -3,120,355 | -4,368,497 | -7,578,005 | -10,609,207 | -21,842,485 | -53,046,035 | -74,264,449 | -371,322,245 |
