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 3,827,725, 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 | 3,827,725 | |
| -1 | -3,827,725 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,827,725.
Example:
1 x 3,827,725 = 3,827,725
and
-1 x -3,827,725 = 3,827,725
Notice both answers equal 3,827,725
With that explanation out of the way, let's continue. Next, we take the number 3,827,725 and divide it by 2:
3,827,725 ÷ 2 = 1,913,862.5
If the quotient is a whole number, then 2 and 1,913,862.5 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 | 3,827,725 | |
| -1 | -3,827,725 |
Now, we try dividing 3,827,725 by 3:
3,827,725 ÷ 3 = 1,275,908.3333
If the quotient is a whole number, then 3 and 1,275,908.3333 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 | 3,827,725 | |
| -1 | -3,827,725 |
Let's try dividing by 4:
3,827,725 ÷ 4 = 956,931.25
If the quotient is a whole number, then 4 and 956,931.25 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 | 3,827,725 | |
| -1 | 3,827,725 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 31 | 55 | 155 | 275 | 341 | 449 | 775 | 1,705 | 2,245 | 4,939 | 8,525 | 11,225 | 13,919 | 24,695 | 69,595 | 123,475 | 153,109 | 347,975 | 765,545 | 3,827,725 |
| -1 | -5 | -11 | -25 | -31 | -55 | -155 | -275 | -341 | -449 | -775 | -1,705 | -2,245 | -4,939 | -8,525 | -11,225 | -13,919 | -24,695 | -69,595 | -123,475 | -153,109 | -347,975 | -765,545 | -3,827,725 |
