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 53,462,447, 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 | 53,462,447 | |
| -1 | -53,462,447 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,462,447.
Example:
1 x 53,462,447 = 53,462,447
and
-1 x -53,462,447 = 53,462,447
Notice both answers equal 53,462,447
With that explanation out of the way, let's continue. Next, we take the number 53,462,447 and divide it by 2:
53,462,447 ÷ 2 = 26,731,223.5
If the quotient is a whole number, then 2 and 26,731,223.5 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 | 53,462,447 | |
| -1 | -53,462,447 |
Now, we try dividing 53,462,447 by 3:
53,462,447 ÷ 3 = 17,820,815.6667
If the quotient is a whole number, then 3 and 17,820,815.6667 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 | 53,462,447 | |
| -1 | -53,462,447 |
Let's try dividing by 4:
53,462,447 ÷ 4 = 13,365,611.75
If the quotient is a whole number, then 4 and 13,365,611.75 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 | 53,462,447 | |
| -1 | 53,462,447 |
If you did it right, you will end up with this table:
| 1 | 19 | 37 | 113 | 673 | 703 | 2,147 | 4,181 | 12,787 | 24,901 | 76,049 | 79,439 | 473,119 | 1,444,931 | 2,813,813 | 53,462,447 |
| -1 | -19 | -37 | -113 | -673 | -703 | -2,147 | -4,181 | -12,787 | -24,901 | -76,049 | -79,439 | -473,119 | -1,444,931 | -2,813,813 | -53,462,447 |
