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 47,422,639, 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 | 47,422,639 | |
| -1 | -47,422,639 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,422,639.
Example:
1 x 47,422,639 = 47,422,639
and
-1 x -47,422,639 = 47,422,639
Notice both answers equal 47,422,639
With that explanation out of the way, let's continue. Next, we take the number 47,422,639 and divide it by 2:
47,422,639 ÷ 2 = 23,711,319.5
If the quotient is a whole number, then 2 and 23,711,319.5 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 | 47,422,639 | |
| -1 | -47,422,639 |
Now, we try dividing 47,422,639 by 3:
47,422,639 ÷ 3 = 15,807,546.3333
If the quotient is a whole number, then 3 and 15,807,546.3333 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 | 47,422,639 | |
| -1 | -47,422,639 |
Let's try dividing by 4:
47,422,639 ÷ 4 = 11,855,659.75
If the quotient is a whole number, then 4 and 11,855,659.75 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 | 47,422,639 | |
| -1 | 47,422,639 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 187 | 367 | 691 | 4,037 | 6,239 | 7,601 | 11,747 | 68,629 | 129,217 | 253,597 | 2,789,567 | 4,311,149 | 47,422,639 |
| -1 | -11 | -17 | -187 | -367 | -691 | -4,037 | -6,239 | -7,601 | -11,747 | -68,629 | -129,217 | -253,597 | -2,789,567 | -4,311,149 | -47,422,639 |
