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 66,274,169, 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 | 66,274,169 | |
| -1 | -66,274,169 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 66,274,169.
Example:
1 x 66,274,169 = 66,274,169
and
-1 x -66,274,169 = 66,274,169
Notice both answers equal 66,274,169
With that explanation out of the way, let's continue. Next, we take the number 66,274,169 and divide it by 2:
66,274,169 ÷ 2 = 33,137,084.5
If the quotient is a whole number, then 2 and 33,137,084.5 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 | 66,274,169 | |
| -1 | -66,274,169 |
Now, we try dividing 66,274,169 by 3:
66,274,169 ÷ 3 = 22,091,389.6667
If the quotient is a whole number, then 3 and 22,091,389.6667 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 | 66,274,169 | |
| -1 | -66,274,169 |
Let's try dividing by 4:
66,274,169 ÷ 4 = 16,568,542.25
If the quotient is a whole number, then 4 and 16,568,542.25 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 | 66,274,169 | |
| -1 | 66,274,169 |
If you did it right, you will end up with this table:
| 1 | 13 | 59 | 71 | 767 | 923 | 1,217 | 4,189 | 15,821 | 54,457 | 71,803 | 86,407 | 933,439 | 1,123,291 | 5,098,013 | 66,274,169 |
| -1 | -13 | -59 | -71 | -767 | -923 | -1,217 | -4,189 | -15,821 | -54,457 | -71,803 | -86,407 | -933,439 | -1,123,291 | -5,098,013 | -66,274,169 |
