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 47,251,075, 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 | 47,251,075 | |
| -1 | -47,251,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,251,075.
Example:
1 x 47,251,075 = 47,251,075
and
-1 x -47,251,075 = 47,251,075
Notice both answers equal 47,251,075
With that explanation out of the way, let's continue. Next, we take the number 47,251,075 and divide it by 2:
47,251,075 ÷ 2 = 23,625,537.5
If the quotient is a whole number, then 2 and 23,625,537.5 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 | 47,251,075 | |
| -1 | -47,251,075 |
Now, we try dividing 47,251,075 by 3:
47,251,075 ÷ 3 = 15,750,358.3333
If the quotient is a whole number, then 3 and 15,750,358.3333 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 | 47,251,075 | |
| -1 | -47,251,075 |
Let's try dividing by 4:
47,251,075 ÷ 4 = 11,812,768.75
If the quotient is a whole number, then 4 and 11,812,768.75 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 | 47,251,075 | |
| -1 | 47,251,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 73 | 85 | 365 | 425 | 1,241 | 1,523 | 1,825 | 6,205 | 7,615 | 25,891 | 31,025 | 38,075 | 111,179 | 129,455 | 555,895 | 647,275 | 1,890,043 | 2,779,475 | 9,450,215 | 47,251,075 |
| -1 | -5 | -17 | -25 | -73 | -85 | -365 | -425 | -1,241 | -1,523 | -1,825 | -6,205 | -7,615 | -25,891 | -31,025 | -38,075 | -111,179 | -129,455 | -555,895 | -647,275 | -1,890,043 | -2,779,475 | -9,450,215 | -47,251,075 |
