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 3,902,525, 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 | 3,902,525 | |
| -1 | -3,902,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,902,525.
Example:
1 x 3,902,525 = 3,902,525
and
-1 x -3,902,525 = 3,902,525
Notice both answers equal 3,902,525
With that explanation out of the way, let's continue. Next, we take the number 3,902,525 and divide it by 2:
3,902,525 ÷ 2 = 1,951,262.5
If the quotient is a whole number, then 2 and 1,951,262.5 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 | 3,902,525 | |
| -1 | -3,902,525 |
Now, we try dividing 3,902,525 by 3:
3,902,525 ÷ 3 = 1,300,841.6667
If the quotient is a whole number, then 3 and 1,300,841.6667 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 | 3,902,525 | |
| -1 | -3,902,525 |
Let's try dividing by 4:
3,902,525 ÷ 4 = 975,631.25
If the quotient is a whole number, then 4 and 975,631.25 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 | 3,902,525 | |
| -1 | 3,902,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 23 | 25 | 55 | 115 | 253 | 275 | 575 | 617 | 1,265 | 3,085 | 6,325 | 6,787 | 14,191 | 15,425 | 33,935 | 70,955 | 156,101 | 169,675 | 354,775 | 780,505 | 3,902,525 |
| -1 | -5 | -11 | -23 | -25 | -55 | -115 | -253 | -275 | -575 | -617 | -1,265 | -3,085 | -6,325 | -6,787 | -14,191 | -15,425 | -33,935 | -70,955 | -156,101 | -169,675 | -354,775 | -780,505 | -3,902,525 |
