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 2,602,615, 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 | 2,602,615 | |
| -1 | -2,602,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,602,615.
Example:
1 x 2,602,615 = 2,602,615
and
-1 x -2,602,615 = 2,602,615
Notice both answers equal 2,602,615
With that explanation out of the way, let's continue. Next, we take the number 2,602,615 and divide it by 2:
2,602,615 ÷ 2 = 1,301,307.5
If the quotient is a whole number, then 2 and 1,301,307.5 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 | 2,602,615 | |
| -1 | -2,602,615 |
Now, we try dividing 2,602,615 by 3:
2,602,615 ÷ 3 = 867,538.3333
If the quotient is a whole number, then 3 and 867,538.3333 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 | 2,602,615 | |
| -1 | -2,602,615 |
Let's try dividing by 4:
2,602,615 ÷ 4 = 650,653.75
If the quotient is a whole number, then 4 and 650,653.75 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 | 2,602,615 | |
| -1 | 2,602,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 67 | 85 | 335 | 457 | 1,139 | 2,285 | 5,695 | 7,769 | 30,619 | 38,845 | 153,095 | 520,523 | 2,602,615 |
| -1 | -5 | -17 | -67 | -85 | -335 | -457 | -1,139 | -2,285 | -5,695 | -7,769 | -30,619 | -38,845 | -153,095 | -520,523 | -2,602,615 |
