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 340,112,425, 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 | 340,112,425 | |
| -1 | -340,112,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 340,112,425.
Example:
1 x 340,112,425 = 340,112,425
and
-1 x -340,112,425 = 340,112,425
Notice both answers equal 340,112,425
With that explanation out of the way, let's continue. Next, we take the number 340,112,425 and divide it by 2:
340,112,425 ÷ 2 = 170,056,212.5
If the quotient is a whole number, then 2 and 170,056,212.5 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 | 340,112,425 | |
| -1 | -340,112,425 |
Now, we try dividing 340,112,425 by 3:
340,112,425 ÷ 3 = 113,370,808.3333
If the quotient is a whole number, then 3 and 113,370,808.3333 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 | 340,112,425 | |
| -1 | -340,112,425 |
Let's try dividing by 4:
340,112,425 ÷ 4 = 85,028,106.25
If the quotient is a whole number, then 4 and 85,028,106.25 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 | 340,112,425 | |
| -1 | 340,112,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 41 | 205 | 389 | 853 | 1,025 | 1,945 | 4,265 | 9,725 | 15,949 | 21,325 | 34,973 | 79,745 | 174,865 | 331,817 | 398,725 | 874,325 | 1,659,085 | 8,295,425 | 13,604,497 | 68,022,485 | 340,112,425 |
| -1 | -5 | -25 | -41 | -205 | -389 | -853 | -1,025 | -1,945 | -4,265 | -9,725 | -15,949 | -21,325 | -34,973 | -79,745 | -174,865 | -331,817 | -398,725 | -874,325 | -1,659,085 | -8,295,425 | -13,604,497 | -68,022,485 | -340,112,425 |
