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 53,324,245, 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 | 53,324,245 | |
| -1 | -53,324,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,324,245.
Example:
1 x 53,324,245 = 53,324,245
and
-1 x -53,324,245 = 53,324,245
Notice both answers equal 53,324,245
With that explanation out of the way, let's continue. Next, we take the number 53,324,245 and divide it by 2:
53,324,245 ÷ 2 = 26,662,122.5
If the quotient is a whole number, then 2 and 26,662,122.5 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 | 53,324,245 | |
| -1 | -53,324,245 |
Now, we try dividing 53,324,245 by 3:
53,324,245 ÷ 3 = 17,774,748.3333
If the quotient is a whole number, then 3 and 17,774,748.3333 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 | 53,324,245 | |
| -1 | -53,324,245 |
Let's try dividing by 4:
53,324,245 ÷ 4 = 13,331,061.25
If the quotient is a whole number, then 4 and 13,331,061.25 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 | 53,324,245 | |
| -1 | 53,324,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 313 | 1,565 | 2,621 | 4,069 | 13,105 | 20,345 | 34,073 | 170,365 | 820,373 | 4,101,865 | 10,664,849 | 53,324,245 |
| -1 | -5 | -13 | -65 | -313 | -1,565 | -2,621 | -4,069 | -13,105 | -20,345 | -34,073 | -170,365 | -820,373 | -4,101,865 | -10,664,849 | -53,324,245 |
