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 47,361,223, 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 | 47,361,223 | |
| -1 | -47,361,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,361,223.
Example:
1 x 47,361,223 = 47,361,223
and
-1 x -47,361,223 = 47,361,223
Notice both answers equal 47,361,223
With that explanation out of the way, let's continue. Next, we take the number 47,361,223 and divide it by 2:
47,361,223 ÷ 2 = 23,680,611.5
If the quotient is a whole number, then 2 and 23,680,611.5 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 | 47,361,223 | |
| -1 | -47,361,223 |
Now, we try dividing 47,361,223 by 3:
47,361,223 ÷ 3 = 15,787,074.3333
If the quotient is a whole number, then 3 and 15,787,074.3333 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 | 47,361,223 | |
| -1 | -47,361,223 |
Let's try dividing by 4:
47,361,223 ÷ 4 = 11,840,305.75
If the quotient is a whole number, then 4 and 11,840,305.75 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 | 47,361,223 | |
| -1 | 47,361,223 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 101 | 707 | 1,313 | 5,153 | 9,191 | 36,071 | 66,989 | 468,923 | 520,453 | 3,643,171 | 6,765,889 | 47,361,223 |
| -1 | -7 | -13 | -91 | -101 | -707 | -1,313 | -5,153 | -9,191 | -36,071 | -66,989 | -468,923 | -520,453 | -3,643,171 | -6,765,889 | -47,361,223 |
