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 738,328,549, 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 | 738,328,549 | |
| -1 | -738,328,549 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 738,328,549.
Example:
1 x 738,328,549 = 738,328,549
and
-1 x -738,328,549 = 738,328,549
Notice both answers equal 738,328,549
With that explanation out of the way, let's continue. Next, we take the number 738,328,549 and divide it by 2:
738,328,549 ÷ 2 = 369,164,274.5
If the quotient is a whole number, then 2 and 369,164,274.5 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 | 738,328,549 | |
| -1 | -738,328,549 |
Now, we try dividing 738,328,549 by 3:
738,328,549 ÷ 3 = 246,109,516.3333
If the quotient is a whole number, then 3 and 246,109,516.3333 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 | 738,328,549 | |
| -1 | -738,328,549 |
Let's try dividing by 4:
738,328,549 ÷ 4 = 184,582,137.25
If the quotient is a whole number, then 4 and 184,582,137.25 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 | 738,328,549 | |
| -1 | 738,328,549 |
If you did it right, you will end up with this table:
| 1 | 7 | 79 | 163 | 553 | 1,141 | 8,191 | 12,877 | 57,337 | 90,139 | 647,089 | 1,335,133 | 4,529,623 | 9,345,931 | 105,475,507 | 738,328,549 |
| -1 | -7 | -79 | -163 | -553 | -1,141 | -8,191 | -12,877 | -57,337 | -90,139 | -647,089 | -1,335,133 | -4,529,623 | -9,345,931 | -105,475,507 | -738,328,549 |
