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 47,031,299, 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 | 47,031,299 | |
| -1 | -47,031,299 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,031,299.
Example:
1 x 47,031,299 = 47,031,299
and
-1 x -47,031,299 = 47,031,299
Notice both answers equal 47,031,299
With that explanation out of the way, let's continue. Next, we take the number 47,031,299 and divide it by 2:
47,031,299 ÷ 2 = 23,515,649.5
If the quotient is a whole number, then 2 and 23,515,649.5 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 | 47,031,299 | |
| -1 | -47,031,299 |
Now, we try dividing 47,031,299 by 3:
47,031,299 ÷ 3 = 15,677,099.6667
If the quotient is a whole number, then 3 and 15,677,099.6667 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 | 47,031,299 | |
| -1 | -47,031,299 |
Let's try dividing by 4:
47,031,299 ÷ 4 = 11,757,824.75
If the quotient is a whole number, then 4 and 11,757,824.75 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 | 47,031,299 | |
| -1 | 47,031,299 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 53 | 119 | 371 | 901 | 6,307 | 7,457 | 52,199 | 126,769 | 395,221 | 887,383 | 2,766,547 | 6,718,757 | 47,031,299 |
| -1 | -7 | -17 | -53 | -119 | -371 | -901 | -6,307 | -7,457 | -52,199 | -126,769 | -395,221 | -887,383 | -2,766,547 | -6,718,757 | -47,031,299 |
