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 38,528,063, 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 | 38,528,063 | |
| -1 | -38,528,063 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 38,528,063.
Example:
1 x 38,528,063 = 38,528,063
and
-1 x -38,528,063 = 38,528,063
Notice both answers equal 38,528,063
With that explanation out of the way, let's continue. Next, we take the number 38,528,063 and divide it by 2:
38,528,063 ÷ 2 = 19,264,031.5
If the quotient is a whole number, then 2 and 19,264,031.5 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 | 38,528,063 | |
| -1 | -38,528,063 |
Now, we try dividing 38,528,063 by 3:
38,528,063 ÷ 3 = 12,842,687.6667
If the quotient is a whole number, then 3 and 12,842,687.6667 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 | 38,528,063 | |
| -1 | -38,528,063 |
Let's try dividing by 4:
38,528,063 ÷ 4 = 9,632,015.75
If the quotient is a whole number, then 4 and 9,632,015.75 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 | 38,528,063 | |
| -1 | 38,528,063 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 49 | 79 | 259 | 269 | 553 | 1,813 | 1,883 | 2,923 | 3,871 | 9,953 | 13,181 | 20,461 | 21,251 | 69,671 | 143,227 | 148,757 | 487,697 | 786,287 | 1,041,299 | 5,504,009 | 38,528,063 |
| -1 | -7 | -37 | -49 | -79 | -259 | -269 | -553 | -1,813 | -1,883 | -2,923 | -3,871 | -9,953 | -13,181 | -20,461 | -21,251 | -69,671 | -143,227 | -148,757 | -487,697 | -786,287 | -1,041,299 | -5,504,009 | -38,528,063 |
