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 53,401,249, 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 | 53,401,249 | |
| -1 | -53,401,249 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,401,249.
Example:
1 x 53,401,249 = 53,401,249
and
-1 x -53,401,249 = 53,401,249
Notice both answers equal 53,401,249
With that explanation out of the way, let's continue. Next, we take the number 53,401,249 and divide it by 2:
53,401,249 ÷ 2 = 26,700,624.5
If the quotient is a whole number, then 2 and 26,700,624.5 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 | 53,401,249 | |
| -1 | -53,401,249 |
Now, we try dividing 53,401,249 by 3:
53,401,249 ÷ 3 = 17,800,416.3333
If the quotient is a whole number, then 3 and 17,800,416.3333 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 | 53,401,249 | |
| -1 | -53,401,249 |
Let's try dividing by 4:
53,401,249 ÷ 4 = 13,350,312.25
If the quotient is a whole number, then 4 and 13,350,312.25 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 | 53,401,249 | |
| -1 | 53,401,249 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 179 | 407 | 733 | 1,969 | 6,623 | 8,063 | 27,121 | 72,853 | 131,207 | 298,331 | 1,443,277 | 4,854,659 | 53,401,249 |
| -1 | -11 | -37 | -179 | -407 | -733 | -1,969 | -6,623 | -8,063 | -27,121 | -72,853 | -131,207 | -298,331 | -1,443,277 | -4,854,659 | -53,401,249 |
