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 353,815,645, 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 | 353,815,645 | |
| -1 | -353,815,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 353,815,645.
Example:
1 x 353,815,645 = 353,815,645
and
-1 x -353,815,645 = 353,815,645
Notice both answers equal 353,815,645
With that explanation out of the way, let's continue. Next, we take the number 353,815,645 and divide it by 2:
353,815,645 ÷ 2 = 176,907,822.5
If the quotient is a whole number, then 2 and 176,907,822.5 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 | 353,815,645 | |
| -1 | -353,815,645 |
Now, we try dividing 353,815,645 by 3:
353,815,645 ÷ 3 = 117,938,548.3333
If the quotient is a whole number, then 3 and 117,938,548.3333 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 | 353,815,645 | |
| -1 | -353,815,645 |
Let's try dividing by 4:
353,815,645 ÷ 4 = 88,453,911.25
If the quotient is a whole number, then 4 and 88,453,911.25 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 | 353,815,645 | |
| -1 | 353,815,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 37 | 85 | 185 | 629 | 3,145 | 112,501 | 562,505 | 1,912,517 | 4,162,537 | 9,562,585 | 20,812,685 | 70,763,129 | 353,815,645 |
| -1 | -5 | -17 | -37 | -85 | -185 | -629 | -3,145 | -112,501 | -562,505 | -1,912,517 | -4,162,537 | -9,562,585 | -20,812,685 | -70,763,129 | -353,815,645 |
