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 52,531,765, 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 | 52,531,765 | |
| -1 | -52,531,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 52,531,765.
Example:
1 x 52,531,765 = 52,531,765
and
-1 x -52,531,765 = 52,531,765
Notice both answers equal 52,531,765
With that explanation out of the way, let's continue. Next, we take the number 52,531,765 and divide it by 2:
52,531,765 ÷ 2 = 26,265,882.5
If the quotient is a whole number, then 2 and 26,265,882.5 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 | 52,531,765 | |
| -1 | -52,531,765 |
Now, we try dividing 52,531,765 by 3:
52,531,765 ÷ 3 = 17,510,588.3333
If the quotient is a whole number, then 3 and 17,510,588.3333 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 | 52,531,765 | |
| -1 | -52,531,765 |
Let's try dividing by 4:
52,531,765 ÷ 4 = 13,132,941.25
If the quotient is a whole number, then 4 and 13,132,941.25 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 | 52,531,765 | |
| -1 | 52,531,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 715 | 73,471 | 367,355 | 808,181 | 955,123 | 4,040,905 | 4,775,615 | 10,506,353 | 52,531,765 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -715 | -73,471 | -367,355 | -808,181 | -955,123 | -4,040,905 | -4,775,615 | -10,506,353 | -52,531,765 |
