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 66,153,703, 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 | 66,153,703 | |
| -1 | -66,153,703 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 66,153,703.
Example:
1 x 66,153,703 = 66,153,703
and
-1 x -66,153,703 = 66,153,703
Notice both answers equal 66,153,703
With that explanation out of the way, let's continue. Next, we take the number 66,153,703 and divide it by 2:
66,153,703 ÷ 2 = 33,076,851.5
If the quotient is a whole number, then 2 and 33,076,851.5 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 | 66,153,703 | |
| -1 | -66,153,703 |
Now, we try dividing 66,153,703 by 3:
66,153,703 ÷ 3 = 22,051,234.3333
If the quotient is a whole number, then 3 and 22,051,234.3333 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 | 66,153,703 | |
| -1 | -66,153,703 |
Let's try dividing by 4:
66,153,703 ÷ 4 = 16,538,425.75
If the quotient is a whole number, then 4 and 16,538,425.75 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 | 66,153,703 | |
| -1 | 66,153,703 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 113 | 791 | 1,243 | 7,603 | 8,701 | 53,221 | 83,633 | 585,431 | 859,139 | 6,013,973 | 9,450,529 | 66,153,703 |
| -1 | -7 | -11 | -77 | -113 | -791 | -1,243 | -7,603 | -8,701 | -53,221 | -83,633 | -585,431 | -859,139 | -6,013,973 | -9,450,529 | -66,153,703 |
