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 415,003,445, 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 | 415,003,445 | |
| -1 | -415,003,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 415,003,445.
Example:
1 x 415,003,445 = 415,003,445
and
-1 x -415,003,445 = 415,003,445
Notice both answers equal 415,003,445
With that explanation out of the way, let's continue. Next, we take the number 415,003,445 and divide it by 2:
415,003,445 ÷ 2 = 207,501,722.5
If the quotient is a whole number, then 2 and 207,501,722.5 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 | 415,003,445 | |
| -1 | -415,003,445 |
Now, we try dividing 415,003,445 by 3:
415,003,445 ÷ 3 = 138,334,481.6667
If the quotient is a whole number, then 3 and 138,334,481.6667 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 | 415,003,445 | |
| -1 | -415,003,445 |
Let's try dividing by 4:
415,003,445 ÷ 4 = 103,750,861.25
If the quotient is a whole number, then 4 and 103,750,861.25 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 | 415,003,445 | |
| -1 | 415,003,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 101 | 179 | 505 | 895 | 4,591 | 18,079 | 22,955 | 90,395 | 463,691 | 821,789 | 2,318,455 | 4,108,945 | 83,000,689 | 415,003,445 |
| -1 | -5 | -101 | -179 | -505 | -895 | -4,591 | -18,079 | -22,955 | -90,395 | -463,691 | -821,789 | -2,318,455 | -4,108,945 | -83,000,689 | -415,003,445 |
