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 444,353,215, 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 | 444,353,215 | |
| -1 | -444,353,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 444,353,215.
Example:
1 x 444,353,215 = 444,353,215
and
-1 x -444,353,215 = 444,353,215
Notice both answers equal 444,353,215
With that explanation out of the way, let's continue. Next, we take the number 444,353,215 and divide it by 2:
444,353,215 ÷ 2 = 222,176,607.5
If the quotient is a whole number, then 2 and 222,176,607.5 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 | 444,353,215 | |
| -1 | -444,353,215 |
Now, we try dividing 444,353,215 by 3:
444,353,215 ÷ 3 = 148,117,738.3333
If the quotient is a whole number, then 3 and 148,117,738.3333 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 | 444,353,215 | |
| -1 | -444,353,215 |
Let's try dividing by 4:
444,353,215 ÷ 4 = 111,088,303.75
If the quotient is a whole number, then 4 and 111,088,303.75 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 | 444,353,215 | |
| -1 | 444,353,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 109 | 115 | 545 | 2,507 | 12,535 | 35,449 | 177,245 | 815,327 | 3,863,941 | 4,076,635 | 19,319,705 | 88,870,643 | 444,353,215 |
| -1 | -5 | -23 | -109 | -115 | -545 | -2,507 | -12,535 | -35,449 | -177,245 | -815,327 | -3,863,941 | -4,076,635 | -19,319,705 | -88,870,643 | -444,353,215 |
