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 53,372,401, 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 | 53,372,401 | |
| -1 | -53,372,401 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,372,401.
Example:
1 x 53,372,401 = 53,372,401
and
-1 x -53,372,401 = 53,372,401
Notice both answers equal 53,372,401
With that explanation out of the way, let's continue. Next, we take the number 53,372,401 and divide it by 2:
53,372,401 ÷ 2 = 26,686,200.5
If the quotient is a whole number, then 2 and 26,686,200.5 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 | 53,372,401 | |
| -1 | -53,372,401 |
Now, we try dividing 53,372,401 by 3:
53,372,401 ÷ 3 = 17,790,800.3333
If the quotient is a whole number, then 3 and 17,790,800.3333 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 | 53,372,401 | |
| -1 | -53,372,401 |
Let's try dividing by 4:
53,372,401 ÷ 4 = 13,343,100.25
If the quotient is a whole number, then 4 and 13,343,100.25 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 | 53,372,401 | |
| -1 | 53,372,401 |
If you did it right, you will end up with this table:
| 1 | 17 | 47 | 67 | 799 | 997 | 1,139 | 3,149 | 16,949 | 46,859 | 53,533 | 66,799 | 796,603 | 1,135,583 | 3,139,553 | 53,372,401 |
| -1 | -17 | -47 | -67 | -799 | -997 | -1,139 | -3,149 | -16,949 | -46,859 | -53,533 | -66,799 | -796,603 | -1,135,583 | -3,139,553 | -53,372,401 |
