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 51,548,875, 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 | 51,548,875 | |
| -1 | -51,548,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,548,875.
Example:
1 x 51,548,875 = 51,548,875
and
-1 x -51,548,875 = 51,548,875
Notice both answers equal 51,548,875
With that explanation out of the way, let's continue. Next, we take the number 51,548,875 and divide it by 2:
51,548,875 ÷ 2 = 25,774,437.5
If the quotient is a whole number, then 2 and 25,774,437.5 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 | 51,548,875 | |
| -1 | -51,548,875 |
Now, we try dividing 51,548,875 by 3:
51,548,875 ÷ 3 = 17,182,958.3333
If the quotient is a whole number, then 3 and 17,182,958.3333 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 | 51,548,875 | |
| -1 | -51,548,875 |
Let's try dividing by 4:
51,548,875 ÷ 4 = 12,887,218.75
If the quotient is a whole number, then 4 and 12,887,218.75 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 | 51,548,875 | |
| -1 | 51,548,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 125 | 175 | 875 | 58,913 | 294,565 | 412,391 | 1,472,825 | 2,061,955 | 7,364,125 | 10,309,775 | 51,548,875 |
| -1 | -5 | -7 | -25 | -35 | -125 | -175 | -875 | -58,913 | -294,565 | -412,391 | -1,472,825 | -2,061,955 | -7,364,125 | -10,309,775 | -51,548,875 |
