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 2,522,525, 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 | 2,522,525 | |
| -1 | -2,522,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,522,525.
Example:
1 x 2,522,525 = 2,522,525
and
-1 x -2,522,525 = 2,522,525
Notice both answers equal 2,522,525
With that explanation out of the way, let's continue. Next, we take the number 2,522,525 and divide it by 2:
2,522,525 ÷ 2 = 1,261,262.5
If the quotient is a whole number, then 2 and 1,261,262.5 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 | 2,522,525 | |
| -1 | -2,522,525 |
Now, we try dividing 2,522,525 by 3:
2,522,525 ÷ 3 = 840,841.6667
If the quotient is a whole number, then 3 and 840,841.6667 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 | 2,522,525 | |
| -1 | -2,522,525 |
Let's try dividing by 4:
2,522,525 ÷ 4 = 630,631.25
If the quotient is a whole number, then 4 and 630,631.25 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 | 2,522,525 | |
| -1 | 2,522,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 41 | 107 | 115 | 205 | 535 | 575 | 943 | 1,025 | 2,461 | 2,675 | 4,387 | 4,715 | 12,305 | 21,935 | 23,575 | 61,525 | 100,901 | 109,675 | 504,505 | 2,522,525 |
| -1 | -5 | -23 | -25 | -41 | -107 | -115 | -205 | -535 | -575 | -943 | -1,025 | -2,461 | -2,675 | -4,387 | -4,715 | -12,305 | -21,935 | -23,575 | -61,525 | -100,901 | -109,675 | -504,505 | -2,522,525 |
