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 416,354,435, 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 | 416,354,435 | |
| -1 | -416,354,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 416,354,435.
Example:
1 x 416,354,435 = 416,354,435
and
-1 x -416,354,435 = 416,354,435
Notice both answers equal 416,354,435
With that explanation out of the way, let's continue. Next, we take the number 416,354,435 and divide it by 2:
416,354,435 ÷ 2 = 208,177,217.5
If the quotient is a whole number, then 2 and 208,177,217.5 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 | 416,354,435 | |
| -1 | -416,354,435 |
Now, we try dividing 416,354,435 by 3:
416,354,435 ÷ 3 = 138,784,811.6667
If the quotient is a whole number, then 3 and 138,784,811.6667 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 | 416,354,435 | |
| -1 | -416,354,435 |
Let's try dividing by 4:
416,354,435 ÷ 4 = 104,088,608.75
If the quotient is a whole number, then 4 and 104,088,608.75 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 | 416,354,435 | |
| -1 | 416,354,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 47 | 235 | 329 | 1,645 | 253,103 | 1,265,515 | 1,771,721 | 8,858,605 | 11,895,841 | 59,479,205 | 83,270,887 | 416,354,435 |
| -1 | -5 | -7 | -35 | -47 | -235 | -329 | -1,645 | -253,103 | -1,265,515 | -1,771,721 | -8,858,605 | -11,895,841 | -59,479,205 | -83,270,887 | -416,354,435 |
