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 3,146,479, 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 | 3,146,479 | |
| -1 | -3,146,479 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,146,479.
Example:
1 x 3,146,479 = 3,146,479
and
-1 x -3,146,479 = 3,146,479
Notice both answers equal 3,146,479
With that explanation out of the way, let's continue. Next, we take the number 3,146,479 and divide it by 2:
3,146,479 ÷ 2 = 1,573,239.5
If the quotient is a whole number, then 2 and 1,573,239.5 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 | 3,146,479 | |
| -1 | -3,146,479 |
Now, we try dividing 3,146,479 by 3:
3,146,479 ÷ 3 = 1,048,826.3333
If the quotient is a whole number, then 3 and 1,048,826.3333 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 | 3,146,479 | |
| -1 | -3,146,479 |
Let's try dividing by 4:
3,146,479 ÷ 4 = 786,619.75
If the quotient is a whole number, then 4 and 786,619.75 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 | 3,146,479 | |
| -1 | 3,146,479 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 137 | 193 | 959 | 1,351 | 2,329 | 3,281 | 16,303 | 22,967 | 26,441 | 185,087 | 449,497 | 3,146,479 |
| -1 | -7 | -17 | -119 | -137 | -193 | -959 | -1,351 | -2,329 | -3,281 | -16,303 | -22,967 | -26,441 | -185,087 | -449,497 | -3,146,479 |
