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 32,619,223, 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 | 32,619,223 | |
| -1 | -32,619,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,619,223.
Example:
1 x 32,619,223 = 32,619,223
and
-1 x -32,619,223 = 32,619,223
Notice both answers equal 32,619,223
With that explanation out of the way, let's continue. Next, we take the number 32,619,223 and divide it by 2:
32,619,223 ÷ 2 = 16,309,611.5
If the quotient is a whole number, then 2 and 16,309,611.5 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 | 32,619,223 | |
| -1 | -32,619,223 |
Now, we try dividing 32,619,223 by 3:
32,619,223 ÷ 3 = 10,873,074.3333
If the quotient is a whole number, then 3 and 10,873,074.3333 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 | 32,619,223 | |
| -1 | -32,619,223 |
Let's try dividing by 4:
32,619,223 ÷ 4 = 8,154,805.75
If the quotient is a whole number, then 4 and 8,154,805.75 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 | 32,619,223 | |
| -1 | 32,619,223 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 31 | 91 | 217 | 373 | 403 | 961 | 2,611 | 2,821 | 4,849 | 6,727 | 11,563 | 12,493 | 33,943 | 80,941 | 87,451 | 150,319 | 358,453 | 1,052,233 | 2,509,171 | 4,659,889 | 32,619,223 |
| -1 | -7 | -13 | -31 | -91 | -217 | -373 | -403 | -961 | -2,611 | -2,821 | -4,849 | -6,727 | -11,563 | -12,493 | -33,943 | -80,941 | -87,451 | -150,319 | -358,453 | -1,052,233 | -2,509,171 | -4,659,889 | -32,619,223 |
