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 66,301,123, 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 | 66,301,123 | |
| -1 | -66,301,123 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 66,301,123.
Example:
1 x 66,301,123 = 66,301,123
and
-1 x -66,301,123 = 66,301,123
Notice both answers equal 66,301,123
With that explanation out of the way, let's continue. Next, we take the number 66,301,123 and divide it by 2:
66,301,123 ÷ 2 = 33,150,561.5
If the quotient is a whole number, then 2 and 33,150,561.5 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 | 66,301,123 | |
| -1 | -66,301,123 |
Now, we try dividing 66,301,123 by 3:
66,301,123 ÷ 3 = 22,100,374.3333
If the quotient is a whole number, then 3 and 22,100,374.3333 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 | 66,301,123 | |
| -1 | -66,301,123 |
Let's try dividing by 4:
66,301,123 ÷ 4 = 16,575,280.75
If the quotient is a whole number, then 4 and 16,575,280.75 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 | 66,301,123 | |
| -1 | 66,301,123 |
If you did it right, you will end up with this table:
| 1 | 7 | 67 | 373 | 379 | 469 | 2,611 | 2,653 | 24,991 | 25,393 | 141,367 | 174,937 | 177,751 | 989,569 | 9,471,589 | 66,301,123 |
| -1 | -7 | -67 | -373 | -379 | -469 | -2,611 | -2,653 | -24,991 | -25,393 | -141,367 | -174,937 | -177,751 | -989,569 | -9,471,589 | -66,301,123 |
