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 4,047,725, 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 | 4,047,725 | |
| -1 | -4,047,725 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,047,725.
Example:
1 x 4,047,725 = 4,047,725
and
-1 x -4,047,725 = 4,047,725
Notice both answers equal 4,047,725
With that explanation out of the way, let's continue. Next, we take the number 4,047,725 and divide it by 2:
4,047,725 ÷ 2 = 2,023,862.5
If the quotient is a whole number, then 2 and 2,023,862.5 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 | 4,047,725 | |
| -1 | -4,047,725 |
Now, we try dividing 4,047,725 by 3:
4,047,725 ÷ 3 = 1,349,241.6667
If the quotient is a whole number, then 3 and 1,349,241.6667 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 | 4,047,725 | |
| -1 | -4,047,725 |
Let's try dividing by 4:
4,047,725 ÷ 4 = 1,011,931.25
If the quotient is a whole number, then 4 and 1,011,931.25 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 | 4,047,725 | |
| -1 | 4,047,725 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 41 | 55 | 205 | 275 | 359 | 451 | 1,025 | 1,795 | 2,255 | 3,949 | 8,975 | 11,275 | 14,719 | 19,745 | 73,595 | 98,725 | 161,909 | 367,975 | 809,545 | 4,047,725 |
| -1 | -5 | -11 | -25 | -41 | -55 | -205 | -275 | -359 | -451 | -1,025 | -1,795 | -2,255 | -3,949 | -8,975 | -11,275 | -14,719 | -19,745 | -73,595 | -98,725 | -161,909 | -367,975 | -809,545 | -4,047,725 |
