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 47,813,143, 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 | 47,813,143 | |
| -1 | -47,813,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 47,813,143.
Example:
1 x 47,813,143 = 47,813,143
and
-1 x -47,813,143 = 47,813,143
Notice both answers equal 47,813,143
With that explanation out of the way, let's continue. Next, we take the number 47,813,143 and divide it by 2:
47,813,143 ÷ 2 = 23,906,571.5
If the quotient is a whole number, then 2 and 23,906,571.5 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 | 47,813,143 | |
| -1 | -47,813,143 |
Now, we try dividing 47,813,143 by 3:
47,813,143 ÷ 3 = 15,937,714.3333
If the quotient is a whole number, then 3 and 15,937,714.3333 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 | 47,813,143 | |
| -1 | -47,813,143 |
Let's try dividing by 4:
47,813,143 ÷ 4 = 11,953,285.75
If the quotient is a whole number, then 4 and 11,953,285.75 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 | 47,813,143 | |
| -1 | 47,813,143 |
If you did it right, you will end up with this table:
| 1 | 7 | 67 | 97 | 469 | 679 | 1,051 | 6,499 | 7,357 | 45,493 | 70,417 | 101,947 | 492,919 | 713,629 | 6,830,449 | 47,813,143 |
| -1 | -7 | -67 | -97 | -469 | -679 | -1,051 | -6,499 | -7,357 | -45,493 | -70,417 | -101,947 | -492,919 | -713,629 | -6,830,449 | -47,813,143 |
