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 51,025,597, 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 | 51,025,597 | |
| -1 | -51,025,597 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,025,597.
Example:
1 x 51,025,597 = 51,025,597
and
-1 x -51,025,597 = 51,025,597
Notice both answers equal 51,025,597
With that explanation out of the way, let's continue. Next, we take the number 51,025,597 and divide it by 2:
51,025,597 ÷ 2 = 25,512,798.5
If the quotient is a whole number, then 2 and 25,512,798.5 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 | 51,025,597 | |
| -1 | -51,025,597 |
Now, we try dividing 51,025,597 by 3:
51,025,597 ÷ 3 = 17,008,532.3333
If the quotient is a whole number, then 3 and 17,008,532.3333 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 | 51,025,597 | |
| -1 | -51,025,597 |
Let's try dividing by 4:
51,025,597 ÷ 4 = 12,756,399.25
If the quotient is a whole number, then 4 and 12,756,399.25 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 | 51,025,597 | |
| -1 | 51,025,597 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 47 | 217 | 329 | 1,457 | 5,003 | 10,199 | 35,021 | 155,093 | 235,141 | 1,085,651 | 1,645,987 | 7,289,371 | 51,025,597 |
| -1 | -7 | -31 | -47 | -217 | -329 | -1,457 | -5,003 | -10,199 | -35,021 | -155,093 | -235,141 | -1,085,651 | -1,645,987 | -7,289,371 | -51,025,597 |
