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 373,874,413, 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 | 373,874,413 | |
| -1 | -373,874,413 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 373,874,413.
Example:
1 x 373,874,413 = 373,874,413
and
-1 x -373,874,413 = 373,874,413
Notice both answers equal 373,874,413
With that explanation out of the way, let's continue. Next, we take the number 373,874,413 and divide it by 2:
373,874,413 ÷ 2 = 186,937,206.5
If the quotient is a whole number, then 2 and 186,937,206.5 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 | 373,874,413 | |
| -1 | -373,874,413 |
Now, we try dividing 373,874,413 by 3:
373,874,413 ÷ 3 = 124,624,804.3333
If the quotient is a whole number, then 3 and 124,624,804.3333 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 | 373,874,413 | |
| -1 | -373,874,413 |
Let's try dividing by 4:
373,874,413 ÷ 4 = 93,468,603.25
If the quotient is a whole number, then 4 and 93,468,603.25 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 | 373,874,413 | |
| -1 | 373,874,413 |
If you did it right, you will end up with this table:
| 1 | 11 | 83 | 283 | 913 | 1,447 | 3,113 | 15,917 | 23,489 | 120,101 | 258,379 | 409,501 | 1,321,111 | 4,504,511 | 33,988,583 | 373,874,413 |
| -1 | -11 | -83 | -283 | -913 | -1,447 | -3,113 | -15,917 | -23,489 | -120,101 | -258,379 | -409,501 | -1,321,111 | -4,504,511 | -33,988,583 | -373,874,413 |
