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 355,615,435, 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 | 355,615,435 | |
| -1 | -355,615,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 355,615,435.
Example:
1 x 355,615,435 = 355,615,435
and
-1 x -355,615,435 = 355,615,435
Notice both answers equal 355,615,435
With that explanation out of the way, let's continue. Next, we take the number 355,615,435 and divide it by 2:
355,615,435 ÷ 2 = 177,807,717.5
If the quotient is a whole number, then 2 and 177,807,717.5 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 | 355,615,435 | |
| -1 | -355,615,435 |
Now, we try dividing 355,615,435 by 3:
355,615,435 ÷ 3 = 118,538,478.3333
If the quotient is a whole number, then 3 and 118,538,478.3333 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 | 355,615,435 | |
| -1 | -355,615,435 |
Let's try dividing by 4:
355,615,435 ÷ 4 = 88,903,858.75
If the quotient is a whole number, then 4 and 88,903,858.75 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 | 355,615,435 | |
| -1 | 355,615,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 597,673 | 2,988,365 | 4,183,711 | 10,160,441 | 20,918,555 | 50,802,205 | 71,123,087 | 355,615,435 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -597,673 | -2,988,365 | -4,183,711 | -10,160,441 | -20,918,555 | -50,802,205 | -71,123,087 | -355,615,435 |
