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 3,548,725, 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 | 3,548,725 | |
| -1 | -3,548,725 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,548,725.
Example:
1 x 3,548,725 = 3,548,725
and
-1 x -3,548,725 = 3,548,725
Notice both answers equal 3,548,725
With that explanation out of the way, let's continue. Next, we take the number 3,548,725 and divide it by 2:
3,548,725 ÷ 2 = 1,774,362.5
If the quotient is a whole number, then 2 and 1,774,362.5 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 | 3,548,725 | |
| -1 | -3,548,725 |
Now, we try dividing 3,548,725 by 3:
3,548,725 ÷ 3 = 1,182,908.3333
If the quotient is a whole number, then 3 and 1,182,908.3333 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 | 3,548,725 | |
| -1 | -3,548,725 |
Let's try dividing by 4:
3,548,725 ÷ 4 = 887,181.25
If the quotient is a whole number, then 4 and 887,181.25 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 | 3,548,725 | |
| -1 | 3,548,725 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 31 | 95 | 155 | 241 | 475 | 589 | 775 | 1,205 | 2,945 | 4,579 | 6,025 | 7,471 | 14,725 | 22,895 | 37,355 | 114,475 | 141,949 | 186,775 | 709,745 | 3,548,725 |
| -1 | -5 | -19 | -25 | -31 | -95 | -155 | -241 | -475 | -589 | -775 | -1,205 | -2,945 | -4,579 | -6,025 | -7,471 | -14,725 | -22,895 | -37,355 | -114,475 | -141,949 | -186,775 | -709,745 | -3,548,725 |
