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 355,126,345, 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 | 355,126,345 | |
| -1 | -355,126,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 355,126,345.
Example:
1 x 355,126,345 = 355,126,345
and
-1 x -355,126,345 = 355,126,345
Notice both answers equal 355,126,345
With that explanation out of the way, let's continue. Next, we take the number 355,126,345 and divide it by 2:
355,126,345 ÷ 2 = 177,563,172.5
If the quotient is a whole number, then 2 and 177,563,172.5 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 | 355,126,345 | |
| -1 | -355,126,345 |
Now, we try dividing 355,126,345 by 3:
355,126,345 ÷ 3 = 118,375,448.3333
If the quotient is a whole number, then 3 and 118,375,448.3333 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 | 355,126,345 | |
| -1 | -355,126,345 |
Let's try dividing by 4:
355,126,345 ÷ 4 = 88,781,586.25
If the quotient is a whole number, then 4 and 88,781,586.25 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 | 355,126,345 | |
| -1 | 355,126,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 596,851 | 2,984,255 | 4,177,957 | 10,146,467 | 20,889,785 | 50,732,335 | 71,025,269 | 355,126,345 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -596,851 | -2,984,255 | -4,177,957 | -10,146,467 | -20,889,785 | -50,732,335 | -71,025,269 | -355,126,345 |
