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 356,216,047, 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 | 356,216,047 | |
| -1 | -356,216,047 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 356,216,047.
Example:
1 x 356,216,047 = 356,216,047
and
-1 x -356,216,047 = 356,216,047
Notice both answers equal 356,216,047
With that explanation out of the way, let's continue. Next, we take the number 356,216,047 and divide it by 2:
356,216,047 ÷ 2 = 178,108,023.5
If the quotient is a whole number, then 2 and 178,108,023.5 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 | 356,216,047 | |
| -1 | -356,216,047 |
Now, we try dividing 356,216,047 by 3:
356,216,047 ÷ 3 = 118,738,682.3333
If the quotient is a whole number, then 3 and 118,738,682.3333 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 | 356,216,047 | |
| -1 | -356,216,047 |
Let's try dividing by 4:
356,216,047 ÷ 4 = 89,054,011.75
If the quotient is a whole number, then 4 and 89,054,011.75 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 | 356,216,047 | |
| -1 | 356,216,047 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 193 | 209 | 2,123 | 3,667 | 8,831 | 40,337 | 97,141 | 167,789 | 1,704,383 | 1,845,679 | 18,748,213 | 32,383,277 | 356,216,047 |
| -1 | -11 | -19 | -193 | -209 | -2,123 | -3,667 | -8,831 | -40,337 | -97,141 | -167,789 | -1,704,383 | -1,845,679 | -18,748,213 | -32,383,277 | -356,216,047 |
