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 52,050,145, 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 | 52,050,145 | |
| -1 | -52,050,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 52,050,145.
Example:
1 x 52,050,145 = 52,050,145
and
-1 x -52,050,145 = 52,050,145
Notice both answers equal 52,050,145
With that explanation out of the way, let's continue. Next, we take the number 52,050,145 and divide it by 2:
52,050,145 ÷ 2 = 26,025,072.5
If the quotient is a whole number, then 2 and 26,025,072.5 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 | 52,050,145 | |
| -1 | -52,050,145 |
Now, we try dividing 52,050,145 by 3:
52,050,145 ÷ 3 = 17,350,048.3333
If the quotient is a whole number, then 3 and 17,350,048.3333 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 | 52,050,145 | |
| -1 | -52,050,145 |
Let's try dividing by 4:
52,050,145 ÷ 4 = 13,012,536.25
If the quotient is a whole number, then 4 and 13,012,536.25 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 | 52,050,145 | |
| -1 | 52,050,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 389 | 1,945 | 2,723 | 3,823 | 13,615 | 19,115 | 26,761 | 133,805 | 1,487,147 | 7,435,735 | 10,410,029 | 52,050,145 |
| -1 | -5 | -7 | -35 | -389 | -1,945 | -2,723 | -3,823 | -13,615 | -19,115 | -26,761 | -133,805 | -1,487,147 | -7,435,735 | -10,410,029 | -52,050,145 |
