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 52,150,985, 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 | 52,150,985 | |
| -1 | -52,150,985 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 52,150,985.
Example:
1 x 52,150,985 = 52,150,985
and
-1 x -52,150,985 = 52,150,985
Notice both answers equal 52,150,985
With that explanation out of the way, let's continue. Next, we take the number 52,150,985 and divide it by 2:
52,150,985 ÷ 2 = 26,075,492.5
If the quotient is a whole number, then 2 and 26,075,492.5 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 | 52,150,985 | |
| -1 | -52,150,985 |
Now, we try dividing 52,150,985 by 3:
52,150,985 ÷ 3 = 17,383,661.6667
If the quotient is a whole number, then 3 and 17,383,661.6667 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 | 52,150,985 | |
| -1 | -52,150,985 |
Let's try dividing by 4:
52,150,985 ÷ 4 = 13,037,746.25
If the quotient is a whole number, then 4 and 13,037,746.25 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 | 52,150,985 | |
| -1 | 52,150,985 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 59 | 85 | 295 | 1,003 | 5,015 | 10,399 | 51,995 | 176,783 | 613,541 | 883,915 | 3,067,705 | 10,430,197 | 52,150,985 |
| -1 | -5 | -17 | -59 | -85 | -295 | -1,003 | -5,015 | -10,399 | -51,995 | -176,783 | -613,541 | -883,915 | -3,067,705 | -10,430,197 | -52,150,985 |
