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 246,543,145, 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 | 246,543,145 | |
| -1 | -246,543,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 246,543,145.
Example:
1 x 246,543,145 = 246,543,145
and
-1 x -246,543,145 = 246,543,145
Notice both answers equal 246,543,145
With that explanation out of the way, let's continue. Next, we take the number 246,543,145 and divide it by 2:
246,543,145 ÷ 2 = 123,271,572.5
If the quotient is a whole number, then 2 and 123,271,572.5 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 | 246,543,145 | |
| -1 | -246,543,145 |
Now, we try dividing 246,543,145 by 3:
246,543,145 ÷ 3 = 82,181,048.3333
If the quotient is a whole number, then 3 and 82,181,048.3333 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 | 246,543,145 | |
| -1 | -246,543,145 |
Let's try dividing by 4:
246,543,145 ÷ 4 = 61,635,786.25
If the quotient is a whole number, then 4 and 61,635,786.25 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 | 246,543,145 | |
| -1 | 246,543,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 137 | 361 | 685 | 997 | 1,805 | 2,603 | 4,985 | 13,015 | 18,943 | 49,457 | 94,715 | 136,589 | 247,285 | 359,917 | 682,945 | 1,799,585 | 2,595,191 | 12,975,955 | 49,308,629 | 246,543,145 |
| -1 | -5 | -19 | -95 | -137 | -361 | -685 | -997 | -1,805 | -2,603 | -4,985 | -13,015 | -18,943 | -49,457 | -94,715 | -136,589 | -247,285 | -359,917 | -682,945 | -1,799,585 | -2,595,191 | -12,975,955 | -49,308,629 | -246,543,145 |
