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 66,710,171, 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 | 66,710,171 | |
| -1 | -66,710,171 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 66,710,171.
Example:
1 x 66,710,171 = 66,710,171
and
-1 x -66,710,171 = 66,710,171
Notice both answers equal 66,710,171
With that explanation out of the way, let's continue. Next, we take the number 66,710,171 and divide it by 2:
66,710,171 ÷ 2 = 33,355,085.5
If the quotient is a whole number, then 2 and 33,355,085.5 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 | 66,710,171 | |
| -1 | -66,710,171 |
Now, we try dividing 66,710,171 by 3:
66,710,171 ÷ 3 = 22,236,723.6667
If the quotient is a whole number, then 3 and 22,236,723.6667 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 | 66,710,171 | |
| -1 | -66,710,171 |
Let's try dividing by 4:
66,710,171 ÷ 4 = 16,677,542.75
If the quotient is a whole number, then 4 and 16,677,542.75 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 | 66,710,171 | |
| -1 | 66,710,171 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 83 | 341 | 913 | 2,357 | 2,573 | 25,927 | 28,303 | 73,067 | 195,631 | 803,737 | 2,151,941 | 6,064,561 | 66,710,171 |
| -1 | -11 | -31 | -83 | -341 | -913 | -2,357 | -2,573 | -25,927 | -28,303 | -73,067 | -195,631 | -803,737 | -2,151,941 | -6,064,561 | -66,710,171 |
