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 66,443,435, 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 | 66,443,435 | |
| -1 | -66,443,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 66,443,435.
Example:
1 x 66,443,435 = 66,443,435
and
-1 x -66,443,435 = 66,443,435
Notice both answers equal 66,443,435
With that explanation out of the way, let's continue. Next, we take the number 66,443,435 and divide it by 2:
66,443,435 ÷ 2 = 33,221,717.5
If the quotient is a whole number, then 2 and 33,221,717.5 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 | 66,443,435 | |
| -1 | -66,443,435 |
Now, we try dividing 66,443,435 by 3:
66,443,435 ÷ 3 = 22,147,811.6667
If the quotient is a whole number, then 3 and 22,147,811.6667 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 | 66,443,435 | |
| -1 | -66,443,435 |
Let's try dividing by 4:
66,443,435 ÷ 4 = 16,610,858.75
If the quotient is a whole number, then 4 and 16,610,858.75 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 | 66,443,435 | |
| -1 | 66,443,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 113 | 115 | 565 | 2,599 | 5,113 | 12,995 | 25,565 | 117,599 | 577,769 | 587,995 | 2,888,845 | 13,288,687 | 66,443,435 |
| -1 | -5 | -23 | -113 | -115 | -565 | -2,599 | -5,113 | -12,995 | -25,565 | -117,599 | -577,769 | -587,995 | -2,888,845 | -13,288,687 | -66,443,435 |
