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 444,540,145, 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 | 444,540,145 | |
| -1 | -444,540,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 444,540,145.
Example:
1 x 444,540,145 = 444,540,145
and
-1 x -444,540,145 = 444,540,145
Notice both answers equal 444,540,145
With that explanation out of the way, let's continue. Next, we take the number 444,540,145 and divide it by 2:
444,540,145 ÷ 2 = 222,270,072.5
If the quotient is a whole number, then 2 and 222,270,072.5 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 | 444,540,145 | |
| -1 | -444,540,145 |
Now, we try dividing 444,540,145 by 3:
444,540,145 ÷ 3 = 148,180,048.3333
If the quotient is a whole number, then 3 and 148,180,048.3333 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 | 444,540,145 | |
| -1 | -444,540,145 |
Let's try dividing by 4:
444,540,145 ÷ 4 = 111,135,036.25
If the quotient is a whole number, then 4 and 111,135,036.25 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 | 444,540,145 | |
| -1 | 444,540,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 419 | 2,095 | 2,933 | 14,665 | 30,313 | 151,565 | 212,191 | 1,060,955 | 12,701,147 | 63,505,735 | 88,908,029 | 444,540,145 |
| -1 | -5 | -7 | -35 | -419 | -2,095 | -2,933 | -14,665 | -30,313 | -151,565 | -212,191 | -1,060,955 | -12,701,147 | -63,505,735 | -88,908,029 | -444,540,145 |
