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 32,977,615, 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 | 32,977,615 | |
| -1 | -32,977,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,977,615.
Example:
1 x 32,977,615 = 32,977,615
and
-1 x -32,977,615 = 32,977,615
Notice both answers equal 32,977,615
With that explanation out of the way, let's continue. Next, we take the number 32,977,615 and divide it by 2:
32,977,615 ÷ 2 = 16,488,807.5
If the quotient is a whole number, then 2 and 16,488,807.5 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 | 32,977,615 | |
| -1 | -32,977,615 |
Now, we try dividing 32,977,615 by 3:
32,977,615 ÷ 3 = 10,992,538.3333
If the quotient is a whole number, then 3 and 10,992,538.3333 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 | 32,977,615 | |
| -1 | -32,977,615 |
Let's try dividing by 4:
32,977,615 ÷ 4 = 8,244,403.75
If the quotient is a whole number, then 4 and 8,244,403.75 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 | 32,977,615 | |
| -1 | 32,977,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 89 | 445 | 979 | 4,895 | 6,737 | 33,685 | 74,107 | 370,535 | 599,593 | 2,997,965 | 6,595,523 | 32,977,615 |
| -1 | -5 | -11 | -55 | -89 | -445 | -979 | -4,895 | -6,737 | -33,685 | -74,107 | -370,535 | -599,593 | -2,997,965 | -6,595,523 | -32,977,615 |
