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 355,623,473, 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 | 355,623,473 | |
| -1 | -355,623,473 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 355,623,473.
Example:
1 x 355,623,473 = 355,623,473
and
-1 x -355,623,473 = 355,623,473
Notice both answers equal 355,623,473
With that explanation out of the way, let's continue. Next, we take the number 355,623,473 and divide it by 2:
355,623,473 ÷ 2 = 177,811,736.5
If the quotient is a whole number, then 2 and 177,811,736.5 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 | 355,623,473 | |
| -1 | -355,623,473 |
Now, we try dividing 355,623,473 by 3:
355,623,473 ÷ 3 = 118,541,157.6667
If the quotient is a whole number, then 3 and 118,541,157.6667 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 | 355,623,473 | |
| -1 | -355,623,473 |
Let's try dividing by 4:
355,623,473 ÷ 4 = 88,905,868.25
If the quotient is a whole number, then 4 and 88,905,868.25 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 | 355,623,473 | |
| -1 | 355,623,473 |
If you did it right, you will end up with this table:
| 1 | 61 | 131 | 191 | 233 | 7,991 | 11,651 | 14,213 | 25,021 | 30,523 | 44,503 | 1,526,281 | 1,861,903 | 2,714,683 | 5,829,893 | 355,623,473 |
| -1 | -61 | -131 | -191 | -233 | -7,991 | -11,651 | -14,213 | -25,021 | -30,523 | -44,503 | -1,526,281 | -1,861,903 | -2,714,683 | -5,829,893 | -355,623,473 |
