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 39,453,601, 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 | 39,453,601 | |
| -1 | -39,453,601 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 39,453,601.
Example:
1 x 39,453,601 = 39,453,601
and
-1 x -39,453,601 = 39,453,601
Notice both answers equal 39,453,601
With that explanation out of the way, let's continue. Next, we take the number 39,453,601 and divide it by 2:
39,453,601 ÷ 2 = 19,726,800.5
If the quotient is a whole number, then 2 and 19,726,800.5 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 | 39,453,601 | |
| -1 | -39,453,601 |
Now, we try dividing 39,453,601 by 3:
39,453,601 ÷ 3 = 13,151,200.3333
If the quotient is a whole number, then 3 and 13,151,200.3333 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 | 39,453,601 | |
| -1 | -39,453,601 |
Let's try dividing by 4:
39,453,601 ÷ 4 = 9,863,400.25
If the quotient is a whole number, then 4 and 9,863,400.25 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 | 39,453,601 | |
| -1 | 39,453,601 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 319 | 337 | 367 | 3,707 | 4,037 | 9,773 | 10,643 | 107,503 | 117,073 | 123,679 | 1,360,469 | 3,586,691 | 39,453,601 |
| -1 | -11 | -29 | -319 | -337 | -367 | -3,707 | -4,037 | -9,773 | -10,643 | -107,503 | -117,073 | -123,679 | -1,360,469 | -3,586,691 | -39,453,601 |
