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 47,070,515, 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 | 47,070,515 | |
| -1 | -47,070,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,070,515.
Example:
1 x 47,070,515 = 47,070,515
and
-1 x -47,070,515 = 47,070,515
Notice both answers equal 47,070,515
With that explanation out of the way, let's continue. Next, we take the number 47,070,515 and divide it by 2:
47,070,515 ÷ 2 = 23,535,257.5
If the quotient is a whole number, then 2 and 23,535,257.5 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 | 47,070,515 | |
| -1 | -47,070,515 |
Now, we try dividing 47,070,515 by 3:
47,070,515 ÷ 3 = 15,690,171.6667
If the quotient is a whole number, then 3 and 15,690,171.6667 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 | 47,070,515 | |
| -1 | -47,070,515 |
Let's try dividing by 4:
47,070,515 ÷ 4 = 11,767,628.75
If the quotient is a whole number, then 4 and 11,767,628.75 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 | 47,070,515 | |
| -1 | 47,070,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 71 | 335 | 355 | 1,979 | 4,757 | 9,895 | 23,785 | 132,593 | 140,509 | 662,965 | 702,545 | 9,414,103 | 47,070,515 |
| -1 | -5 | -67 | -71 | -335 | -355 | -1,979 | -4,757 | -9,895 | -23,785 | -132,593 | -140,509 | -662,965 | -702,545 | -9,414,103 | -47,070,515 |
