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 47,736,731, 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 | 47,736,731 | |
| -1 | -47,736,731 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,736,731.
Example:
1 x 47,736,731 = 47,736,731
and
-1 x -47,736,731 = 47,736,731
Notice both answers equal 47,736,731
With that explanation out of the way, let's continue. Next, we take the number 47,736,731 and divide it by 2:
47,736,731 ÷ 2 = 23,868,365.5
If the quotient is a whole number, then 2 and 23,868,365.5 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 | 47,736,731 | |
| -1 | -47,736,731 |
Now, we try dividing 47,736,731 by 3:
47,736,731 ÷ 3 = 15,912,243.6667
If the quotient is a whole number, then 3 and 15,912,243.6667 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 | 47,736,731 | |
| -1 | -47,736,731 |
Let's try dividing by 4:
47,736,731 ÷ 4 = 11,934,182.75
If the quotient is a whole number, then 4 and 11,934,182.75 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 | 47,736,731 | |
| -1 | 47,736,731 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 49 | 119 | 289 | 833 | 2,023 | 3,371 | 14,161 | 23,597 | 57,307 | 165,179 | 401,149 | 974,219 | 2,808,043 | 6,819,533 | 47,736,731 |
| -1 | -7 | -17 | -49 | -119 | -289 | -833 | -2,023 | -3,371 | -14,161 | -23,597 | -57,307 | -165,179 | -401,149 | -974,219 | -2,808,043 | -6,819,533 | -47,736,731 |
