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 148,136,765, 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 | 148,136,765 | |
| -1 | -148,136,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 148,136,765.
Example:
1 x 148,136,765 = 148,136,765
and
-1 x -148,136,765 = 148,136,765
Notice both answers equal 148,136,765
With that explanation out of the way, let's continue. Next, we take the number 148,136,765 and divide it by 2:
148,136,765 ÷ 2 = 74,068,382.5
If the quotient is a whole number, then 2 and 74,068,382.5 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 | 148,136,765 | |
| -1 | -148,136,765 |
Now, we try dividing 148,136,765 by 3:
148,136,765 ÷ 3 = 49,378,921.6667
If the quotient is a whole number, then 3 and 49,378,921.6667 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 | 148,136,765 | |
| -1 | -148,136,765 |
Let's try dividing by 4:
148,136,765 ÷ 4 = 37,034,191.25
If the quotient is a whole number, then 4 and 37,034,191.25 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 | 148,136,765 | |
| -1 | 148,136,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 131 | 655 | 917 | 4,585 | 32,309 | 161,545 | 226,163 | 1,130,815 | 4,232,479 | 21,162,395 | 29,627,353 | 148,136,765 |
| -1 | -5 | -7 | -35 | -131 | -655 | -917 | -4,585 | -32,309 | -161,545 | -226,163 | -1,130,815 | -4,232,479 | -21,162,395 | -29,627,353 | -148,136,765 |
