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 32,211,773, 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 | 32,211,773 | |
| -1 | -32,211,773 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,211,773.
Example:
1 x 32,211,773 = 32,211,773
and
-1 x -32,211,773 = 32,211,773
Notice both answers equal 32,211,773
With that explanation out of the way, let's continue. Next, we take the number 32,211,773 and divide it by 2:
32,211,773 ÷ 2 = 16,105,886.5
If the quotient is a whole number, then 2 and 16,105,886.5 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 | 32,211,773 | |
| -1 | -32,211,773 |
Now, we try dividing 32,211,773 by 3:
32,211,773 ÷ 3 = 10,737,257.6667
If the quotient is a whole number, then 3 and 10,737,257.6667 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 | 32,211,773 | |
| -1 | -32,211,773 |
Let's try dividing by 4:
32,211,773 ÷ 4 = 8,052,943.25
If the quotient is a whole number, then 4 and 8,052,943.25 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 | 32,211,773 | |
| -1 | 32,211,773 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 43 | 121 | 151 | 451 | 473 | 1,661 | 1,763 | 4,961 | 5,203 | 6,191 | 6,493 | 18,271 | 19,393 | 68,101 | 71,423 | 213,323 | 266,213 | 749,111 | 785,653 | 2,928,343 | 32,211,773 |
| -1 | -11 | -41 | -43 | -121 | -151 | -451 | -473 | -1,661 | -1,763 | -4,961 | -5,203 | -6,191 | -6,493 | -18,271 | -19,393 | -68,101 | -71,423 | -213,323 | -266,213 | -749,111 | -785,653 | -2,928,343 | -32,211,773 |
