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 43,212,533, 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 | 43,212,533 | |
| -1 | -43,212,533 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,212,533.
Example:
1 x 43,212,533 = 43,212,533
and
-1 x -43,212,533 = 43,212,533
Notice both answers equal 43,212,533
With that explanation out of the way, let's continue. Next, we take the number 43,212,533 and divide it by 2:
43,212,533 ÷ 2 = 21,606,266.5
If the quotient is a whole number, then 2 and 21,606,266.5 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 | 43,212,533 | |
| -1 | -43,212,533 |
Now, we try dividing 43,212,533 by 3:
43,212,533 ÷ 3 = 14,404,177.6667
If the quotient is a whole number, then 3 and 14,404,177.6667 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 | 43,212,533 | |
| -1 | -43,212,533 |
Let's try dividing by 4:
43,212,533 ÷ 4 = 10,803,133.25
If the quotient is a whole number, then 4 and 10,803,133.25 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 | 43,212,533 | |
| -1 | 43,212,533 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 149 | 1,043 | 1,937 | 3,187 | 13,559 | 22,309 | 41,431 | 290,017 | 474,863 | 3,324,041 | 6,173,219 | 43,212,533 |
| -1 | -7 | -13 | -91 | -149 | -1,043 | -1,937 | -3,187 | -13,559 | -22,309 | -41,431 | -290,017 | -474,863 | -3,324,041 | -6,173,219 | -43,212,533 |
