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 51,628,307, 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 | 51,628,307 | |
| -1 | -51,628,307 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,628,307.
Example:
1 x 51,628,307 = 51,628,307
and
-1 x -51,628,307 = 51,628,307
Notice both answers equal 51,628,307
With that explanation out of the way, let's continue. Next, we take the number 51,628,307 and divide it by 2:
51,628,307 ÷ 2 = 25,814,153.5
If the quotient is a whole number, then 2 and 25,814,153.5 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 | 51,628,307 | |
| -1 | -51,628,307 |
Now, we try dividing 51,628,307 by 3:
51,628,307 ÷ 3 = 17,209,435.6667
If the quotient is a whole number, then 3 and 17,209,435.6667 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 | 51,628,307 | |
| -1 | -51,628,307 |
Let's try dividing by 4:
51,628,307 ÷ 4 = 12,907,076.75
If the quotient is a whole number, then 4 and 12,907,076.75 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 | 51,628,307 | |
| -1 | 51,628,307 |
If you did it right, you will end up with this table:
| 1 | 23 | 41 | 53 | 943 | 1,033 | 1,219 | 2,173 | 23,759 | 42,353 | 49,979 | 54,749 | 974,119 | 1,259,227 | 2,244,709 | 51,628,307 |
| -1 | -23 | -41 | -53 | -943 | -1,033 | -1,219 | -2,173 | -23,759 | -42,353 | -49,979 | -54,749 | -974,119 | -1,259,227 | -2,244,709 | -51,628,307 |
