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 52,213,145, 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 | 52,213,145 | |
| -1 | -52,213,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 52,213,145.
Example:
1 x 52,213,145 = 52,213,145
and
-1 x -52,213,145 = 52,213,145
Notice both answers equal 52,213,145
With that explanation out of the way, let's continue. Next, we take the number 52,213,145 and divide it by 2:
52,213,145 ÷ 2 = 26,106,572.5
If the quotient is a whole number, then 2 and 26,106,572.5 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 | 52,213,145 | |
| -1 | -52,213,145 |
Now, we try dividing 52,213,145 by 3:
52,213,145 ÷ 3 = 17,404,381.6667
If the quotient is a whole number, then 3 and 17,404,381.6667 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 | 52,213,145 | |
| -1 | -52,213,145 |
Let's try dividing by 4:
52,213,145 ÷ 4 = 13,053,286.25
If the quotient is a whole number, then 4 and 13,053,286.25 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 | 52,213,145 | |
| -1 | 52,213,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 229 | 1,145 | 1,471 | 7,099 | 7,355 | 35,495 | 45,601 | 228,005 | 336,859 | 1,684,295 | 10,442,629 | 52,213,145 |
| -1 | -5 | -31 | -155 | -229 | -1,145 | -1,471 | -7,099 | -7,355 | -35,495 | -45,601 | -228,005 | -336,859 | -1,684,295 | -10,442,629 | -52,213,145 |
