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 212,532,061, 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 | 212,532,061 | |
| -1 | -212,532,061 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 212,532,061.
Example:
1 x 212,532,061 = 212,532,061
and
-1 x -212,532,061 = 212,532,061
Notice both answers equal 212,532,061
With that explanation out of the way, let's continue. Next, we take the number 212,532,061 and divide it by 2:
212,532,061 ÷ 2 = 106,266,030.5
If the quotient is a whole number, then 2 and 106,266,030.5 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 | 212,532,061 | |
| -1 | -212,532,061 |
Now, we try dividing 212,532,061 by 3:
212,532,061 ÷ 3 = 70,844,020.3333
If the quotient is a whole number, then 3 and 70,844,020.3333 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 | 212,532,061 | |
| -1 | -212,532,061 |
Let's try dividing by 4:
212,532,061 ÷ 4 = 53,133,015.25
If the quotient is a whole number, then 4 and 53,133,015.25 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 | 212,532,061 | |
| -1 | 212,532,061 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 257 | 343 | 1,799 | 2,411 | 12,593 | 16,877 | 88,151 | 118,139 | 619,627 | 826,973 | 4,337,389 | 30,361,723 | 212,532,061 |
| -1 | -7 | -49 | -257 | -343 | -1,799 | -2,411 | -12,593 | -16,877 | -88,151 | -118,139 | -619,627 | -826,973 | -4,337,389 | -30,361,723 | -212,532,061 |
