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 602,741,363, 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 | 602,741,363 | |
| -1 | -602,741,363 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 602,741,363.
Example:
1 x 602,741,363 = 602,741,363
and
-1 x -602,741,363 = 602,741,363
Notice both answers equal 602,741,363
With that explanation out of the way, let's continue. Next, we take the number 602,741,363 and divide it by 2:
602,741,363 ÷ 2 = 301,370,681.5
If the quotient is a whole number, then 2 and 301,370,681.5 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 | 602,741,363 | |
| -1 | -602,741,363 |
Now, we try dividing 602,741,363 by 3:
602,741,363 ÷ 3 = 200,913,787.6667
If the quotient is a whole number, then 3 and 200,913,787.6667 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 | 602,741,363 | |
| -1 | -602,741,363 |
Let's try dividing by 4:
602,741,363 ÷ 4 = 150,685,340.75
If the quotient is a whole number, then 4 and 150,685,340.75 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 | 602,741,363 | |
| -1 | 602,741,363 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 73 | 301 | 511 | 3,139 | 21,973 | 27,431 | 192,017 | 1,179,533 | 2,002,463 | 8,256,731 | 14,017,241 | 86,105,909 | 602,741,363 |
| -1 | -7 | -43 | -73 | -301 | -511 | -3,139 | -21,973 | -27,431 | -192,017 | -1,179,533 | -2,002,463 | -8,256,731 | -14,017,241 | -86,105,909 | -602,741,363 |
