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 2,520,635, 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 | 2,520,635 | |
| -1 | -2,520,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,520,635.
Example:
1 x 2,520,635 = 2,520,635
and
-1 x -2,520,635 = 2,520,635
Notice both answers equal 2,520,635
With that explanation out of the way, let's continue. Next, we take the number 2,520,635 and divide it by 2:
2,520,635 ÷ 2 = 1,260,317.5
If the quotient is a whole number, then 2 and 1,260,317.5 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 | 2,520,635 | |
| -1 | -2,520,635 |
Now, we try dividing 2,520,635 by 3:
2,520,635 ÷ 3 = 840,211.6667
If the quotient is a whole number, then 3 and 840,211.6667 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 | 2,520,635 | |
| -1 | -2,520,635 |
Let's try dividing by 4:
2,520,635 ÷ 4 = 630,158.75
If the quotient is a whole number, then 4 and 630,158.75 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 | 2,520,635 | |
| -1 | 2,520,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 95 | 157 | 169 | 247 | 785 | 845 | 1,235 | 2,041 | 2,983 | 3,211 | 10,205 | 14,915 | 16,055 | 26,533 | 38,779 | 132,665 | 193,895 | 504,127 | 2,520,635 |
| -1 | -5 | -13 | -19 | -65 | -95 | -157 | -169 | -247 | -785 | -845 | -1,235 | -2,041 | -2,983 | -3,211 | -10,205 | -14,915 | -16,055 | -26,533 | -38,779 | -132,665 | -193,895 | -504,127 | -2,520,635 |
