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 602,407,111, 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 | 602,407,111 | |
| -1 | -602,407,111 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 602,407,111.
Example:
1 x 602,407,111 = 602,407,111
and
-1 x -602,407,111 = 602,407,111
Notice both answers equal 602,407,111
With that explanation out of the way, let's continue. Next, we take the number 602,407,111 and divide it by 2:
602,407,111 ÷ 2 = 301,203,555.5
If the quotient is a whole number, then 2 and 301,203,555.5 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 | 602,407,111 | |
| -1 | -602,407,111 |
Now, we try dividing 602,407,111 by 3:
602,407,111 ÷ 3 = 200,802,370.3333
If the quotient is a whole number, then 3 and 200,802,370.3333 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 | 602,407,111 | |
| -1 | -602,407,111 |
Let's try dividing by 4:
602,407,111 ÷ 4 = 150,601,777.75
If the quotient is a whole number, then 4 and 150,601,777.75 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 | 602,407,111 | |
| -1 | 602,407,111 |
If you did it right, you will end up with this table:
| 1 | 29 | 83 | 107 | 2,339 | 2,407 | 3,103 | 8,881 | 67,831 | 194,137 | 250,273 | 257,549 | 5,629,973 | 7,257,917 | 20,772,659 | 602,407,111 |
| -1 | -29 | -83 | -107 | -2,339 | -2,407 | -3,103 | -8,881 | -67,831 | -194,137 | -250,273 | -257,549 | -5,629,973 | -7,257,917 | -20,772,659 | -602,407,111 |
