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 32,611,615, 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 | 32,611,615 | |
| -1 | -32,611,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,611,615.
Example:
1 x 32,611,615 = 32,611,615
and
-1 x -32,611,615 = 32,611,615
Notice both answers equal 32,611,615
With that explanation out of the way, let's continue. Next, we take the number 32,611,615 and divide it by 2:
32,611,615 ÷ 2 = 16,305,807.5
If the quotient is a whole number, then 2 and 16,305,807.5 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 | 32,611,615 | |
| -1 | -32,611,615 |
Now, we try dividing 32,611,615 by 3:
32,611,615 ÷ 3 = 10,870,538.3333
If the quotient is a whole number, then 3 and 10,870,538.3333 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 | 32,611,615 | |
| -1 | -32,611,615 |
Let's try dividing by 4:
32,611,615 ÷ 4 = 8,152,903.75
If the quotient is a whole number, then 4 and 8,152,903.75 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 | 32,611,615 | |
| -1 | 32,611,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 185 | 409 | 431 | 2,045 | 2,155 | 15,133 | 15,947 | 75,665 | 79,735 | 176,279 | 881,395 | 6,522,323 | 32,611,615 |
| -1 | -5 | -37 | -185 | -409 | -431 | -2,045 | -2,155 | -15,133 | -15,947 | -75,665 | -79,735 | -176,279 | -881,395 | -6,522,323 | -32,611,615 |
