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 445,324,355, 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 | 445,324,355 | |
| -1 | -445,324,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 445,324,355.
Example:
1 x 445,324,355 = 445,324,355
and
-1 x -445,324,355 = 445,324,355
Notice both answers equal 445,324,355
With that explanation out of the way, let's continue. Next, we take the number 445,324,355 and divide it by 2:
445,324,355 ÷ 2 = 222,662,177.5
If the quotient is a whole number, then 2 and 222,662,177.5 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 | 445,324,355 | |
| -1 | -445,324,355 |
Now, we try dividing 445,324,355 by 3:
445,324,355 ÷ 3 = 148,441,451.6667
If the quotient is a whole number, then 3 and 148,441,451.6667 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 | 445,324,355 | |
| -1 | -445,324,355 |
Let's try dividing by 4:
445,324,355 ÷ 4 = 111,331,088.75
If the quotient is a whole number, then 4 and 111,331,088.75 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 | 445,324,355 | |
| -1 | 445,324,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 2,797 | 4,549 | 13,985 | 19,579 | 22,745 | 31,843 | 97,895 | 159,215 | 12,723,553 | 63,617,765 | 89,064,871 | 445,324,355 |
| -1 | -5 | -7 | -35 | -2,797 | -4,549 | -13,985 | -19,579 | -22,745 | -31,843 | -97,895 | -159,215 | -12,723,553 | -63,617,765 | -89,064,871 | -445,324,355 |
