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 4,227,025, 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 | 4,227,025 | |
| -1 | -4,227,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,227,025.
Example:
1 x 4,227,025 = 4,227,025
and
-1 x -4,227,025 = 4,227,025
Notice both answers equal 4,227,025
With that explanation out of the way, let's continue. Next, we take the number 4,227,025 and divide it by 2:
4,227,025 ÷ 2 = 2,113,512.5
If the quotient is a whole number, then 2 and 2,113,512.5 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 | 4,227,025 | |
| -1 | -4,227,025 |
Now, we try dividing 4,227,025 by 3:
4,227,025 ÷ 3 = 1,409,008.3333
If the quotient is a whole number, then 3 and 1,409,008.3333 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 | 4,227,025 | |
| -1 | -4,227,025 |
Let's try dividing by 4:
4,227,025 ÷ 4 = 1,056,756.25
If the quotient is a whole number, then 4 and 1,056,756.25 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 | 4,227,025 | |
| -1 | 4,227,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 19 | 25 | 55 | 95 | 209 | 275 | 475 | 809 | 1,045 | 4,045 | 5,225 | 8,899 | 15,371 | 20,225 | 44,495 | 76,855 | 169,081 | 222,475 | 384,275 | 845,405 | 4,227,025 |
| -1 | -5 | -11 | -19 | -25 | -55 | -95 | -209 | -275 | -475 | -809 | -1,045 | -4,045 | -5,225 | -8,899 | -15,371 | -20,225 | -44,495 | -76,855 | -169,081 | -222,475 | -384,275 | -845,405 | -4,227,025 |
