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 228,850,615, 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 | 228,850,615 | |
| -1 | -228,850,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 228,850,615.
Example:
1 x 228,850,615 = 228,850,615
and
-1 x -228,850,615 = 228,850,615
Notice both answers equal 228,850,615
With that explanation out of the way, let's continue. Next, we take the number 228,850,615 and divide it by 2:
228,850,615 ÷ 2 = 114,425,307.5
If the quotient is a whole number, then 2 and 114,425,307.5 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 | 228,850,615 | |
| -1 | -228,850,615 |
Now, we try dividing 228,850,615 by 3:
228,850,615 ÷ 3 = 76,283,538.3333
If the quotient is a whole number, then 3 and 76,283,538.3333 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 | 228,850,615 | |
| -1 | -228,850,615 |
Let's try dividing by 4:
228,850,615 ÷ 4 = 57,212,653.75
If the quotient is a whole number, then 4 and 57,212,653.75 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 | 228,850,615 | |
| -1 | 228,850,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 281 | 1,405 | 1,967 | 9,835 | 23,269 | 116,345 | 162,883 | 814,415 | 6,538,589 | 32,692,945 | 45,770,123 | 228,850,615 |
| -1 | -5 | -7 | -35 | -281 | -1,405 | -1,967 | -9,835 | -23,269 | -116,345 | -162,883 | -814,415 | -6,538,589 | -32,692,945 | -45,770,123 | -228,850,615 |
