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 53,974,847, 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 | 53,974,847 | |
| -1 | -53,974,847 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,974,847.
Example:
1 x 53,974,847 = 53,974,847
and
-1 x -53,974,847 = 53,974,847
Notice both answers equal 53,974,847
With that explanation out of the way, let's continue. Next, we take the number 53,974,847 and divide it by 2:
53,974,847 ÷ 2 = 26,987,423.5
If the quotient is a whole number, then 2 and 26,987,423.5 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 | 53,974,847 | |
| -1 | -53,974,847 |
Now, we try dividing 53,974,847 by 3:
53,974,847 ÷ 3 = 17,991,615.6667
If the quotient is a whole number, then 3 and 17,991,615.6667 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 | 53,974,847 | |
| -1 | -53,974,847 |
Let's try dividing by 4:
53,974,847 ÷ 4 = 13,493,711.75
If the quotient is a whole number, then 4 and 13,493,711.75 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 | 53,974,847 | |
| -1 | 53,974,847 |
If you did it right, you will end up with this table:
| 1 | 17 | 43 | 47 | 731 | 799 | 1,571 | 2,021 | 26,707 | 34,357 | 67,553 | 73,837 | 1,148,401 | 1,255,229 | 3,174,991 | 53,974,847 |
| -1 | -17 | -43 | -47 | -731 | -799 | -1,571 | -2,021 | -26,707 | -34,357 | -67,553 | -73,837 | -1,148,401 | -1,255,229 | -3,174,991 | -53,974,847 |
