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 47,687,675, 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 | 47,687,675 | |
| -1 | -47,687,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,687,675.
Example:
1 x 47,687,675 = 47,687,675
and
-1 x -47,687,675 = 47,687,675
Notice both answers equal 47,687,675
With that explanation out of the way, let's continue. Next, we take the number 47,687,675 and divide it by 2:
47,687,675 ÷ 2 = 23,843,837.5
If the quotient is a whole number, then 2 and 23,843,837.5 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 | 47,687,675 | |
| -1 | -47,687,675 |
Now, we try dividing 47,687,675 by 3:
47,687,675 ÷ 3 = 15,895,891.6667
If the quotient is a whole number, then 3 and 15,895,891.6667 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 | 47,687,675 | |
| -1 | -47,687,675 |
Let's try dividing by 4:
47,687,675 ÷ 4 = 11,921,918.75
If the quotient is a whole number, then 4 and 11,921,918.75 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 | 47,687,675 | |
| -1 | 47,687,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 379 | 719 | 1,895 | 2,653 | 3,595 | 5,033 | 9,475 | 13,265 | 17,975 | 25,165 | 66,325 | 125,825 | 272,501 | 1,362,505 | 1,907,507 | 6,812,525 | 9,537,535 | 47,687,675 |
| -1 | -5 | -7 | -25 | -35 | -175 | -379 | -719 | -1,895 | -2,653 | -3,595 | -5,033 | -9,475 | -13,265 | -17,975 | -25,165 | -66,325 | -125,825 | -272,501 | -1,362,505 | -1,907,507 | -6,812,525 | -9,537,535 | -47,687,675 |
