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 54,071,747, 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 | 54,071,747 | |
| -1 | -54,071,747 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,071,747.
Example:
1 x 54,071,747 = 54,071,747
and
-1 x -54,071,747 = 54,071,747
Notice both answers equal 54,071,747
With that explanation out of the way, let's continue. Next, we take the number 54,071,747 and divide it by 2:
54,071,747 ÷ 2 = 27,035,873.5
If the quotient is a whole number, then 2 and 27,035,873.5 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 | 54,071,747 | |
| -1 | -54,071,747 |
Now, we try dividing 54,071,747 by 3:
54,071,747 ÷ 3 = 18,023,915.6667
If the quotient is a whole number, then 3 and 18,023,915.6667 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 | 54,071,747 | |
| -1 | -54,071,747 |
Let's try dividing by 4:
54,071,747 ÷ 4 = 13,517,936.75
If the quotient is a whole number, then 4 and 13,517,936.75 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 | 54,071,747 | |
| -1 | 54,071,747 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 67 | 493 | 1,139 | 1,637 | 1,943 | 27,829 | 33,031 | 47,473 | 109,679 | 807,041 | 1,864,543 | 3,180,691 | 54,071,747 |
| -1 | -17 | -29 | -67 | -493 | -1,139 | -1,637 | -1,943 | -27,829 | -33,031 | -47,473 | -109,679 | -807,041 | -1,864,543 | -3,180,691 | -54,071,747 |
