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 354,805,373, 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 | 354,805,373 | |
| -1 | -354,805,373 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 354,805,373.
Example:
1 x 354,805,373 = 354,805,373
and
-1 x -354,805,373 = 354,805,373
Notice both answers equal 354,805,373
With that explanation out of the way, let's continue. Next, we take the number 354,805,373 and divide it by 2:
354,805,373 ÷ 2 = 177,402,686.5
If the quotient is a whole number, then 2 and 177,402,686.5 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 | 354,805,373 | |
| -1 | -354,805,373 |
Now, we try dividing 354,805,373 by 3:
354,805,373 ÷ 3 = 118,268,457.6667
If the quotient is a whole number, then 3 and 118,268,457.6667 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 | 354,805,373 | |
| -1 | -354,805,373 |
Let's try dividing by 4:
354,805,373 ÷ 4 = 88,701,343.25
If the quotient is a whole number, then 4 and 88,701,343.25 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 | 354,805,373 | |
| -1 | 354,805,373 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 53 | 247 | 689 | 1,007 | 13,091 | 27,103 | 352,339 | 514,957 | 1,436,459 | 6,694,441 | 18,673,967 | 27,292,721 | 354,805,373 |
| -1 | -13 | -19 | -53 | -247 | -689 | -1,007 | -13,091 | -27,103 | -352,339 | -514,957 | -1,436,459 | -6,694,441 | -18,673,967 | -27,292,721 | -354,805,373 |
