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 306,136,615, 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 | 306,136,615 | |
| -1 | -306,136,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 306,136,615.
Example:
1 x 306,136,615 = 306,136,615
and
-1 x -306,136,615 = 306,136,615
Notice both answers equal 306,136,615
With that explanation out of the way, let's continue. Next, we take the number 306,136,615 and divide it by 2:
306,136,615 ÷ 2 = 153,068,307.5
If the quotient is a whole number, then 2 and 153,068,307.5 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 | 306,136,615 | |
| -1 | -306,136,615 |
Now, we try dividing 306,136,615 by 3:
306,136,615 ÷ 3 = 102,045,538.3333
If the quotient is a whole number, then 3 and 102,045,538.3333 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 | 306,136,615 | |
| -1 | -306,136,615 |
Let's try dividing by 4:
306,136,615 ÷ 4 = 76,534,153.75
If the quotient is a whole number, then 4 and 76,534,153.75 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 | 306,136,615 | |
| -1 | 306,136,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 47 | 145 | 235 | 841 | 1,363 | 1,549 | 4,205 | 6,815 | 7,745 | 39,527 | 44,921 | 72,803 | 197,635 | 224,605 | 364,015 | 1,302,709 | 2,111,287 | 6,513,545 | 10,556,435 | 61,227,323 | 306,136,615 |
| -1 | -5 | -29 | -47 | -145 | -235 | -841 | -1,363 | -1,549 | -4,205 | -6,815 | -7,745 | -39,527 | -44,921 | -72,803 | -197,635 | -224,605 | -364,015 | -1,302,709 | -2,111,287 | -6,513,545 | -10,556,435 | -61,227,323 | -306,136,615 |
