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 47,623,615, 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 | 47,623,615 | |
| -1 | -47,623,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,623,615.
Example:
1 x 47,623,615 = 47,623,615
and
-1 x -47,623,615 = 47,623,615
Notice both answers equal 47,623,615
With that explanation out of the way, let's continue. Next, we take the number 47,623,615 and divide it by 2:
47,623,615 ÷ 2 = 23,811,807.5
If the quotient is a whole number, then 2 and 23,811,807.5 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 | 47,623,615 | |
| -1 | -47,623,615 |
Now, we try dividing 47,623,615 by 3:
47,623,615 ÷ 3 = 15,874,538.3333
If the quotient is a whole number, then 3 and 15,874,538.3333 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 | 47,623,615 | |
| -1 | -47,623,615 |
Let's try dividing by 4:
47,623,615 ÷ 4 = 11,905,903.75
If the quotient is a whole number, then 4 and 11,905,903.75 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 | 47,623,615 | |
| -1 | 47,623,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 61 | 65 | 305 | 793 | 3,965 | 12,011 | 60,055 | 156,143 | 732,671 | 780,715 | 3,663,355 | 9,524,723 | 47,623,615 |
| -1 | -5 | -13 | -61 | -65 | -305 | -793 | -3,965 | -12,011 | -60,055 | -156,143 | -732,671 | -780,715 | -3,663,355 | -9,524,723 | -47,623,615 |
