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 360,342,745, 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 | 360,342,745 | |
| -1 | -360,342,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 360,342,745.
Example:
1 x 360,342,745 = 360,342,745
and
-1 x -360,342,745 = 360,342,745
Notice both answers equal 360,342,745
With that explanation out of the way, let's continue. Next, we take the number 360,342,745 and divide it by 2:
360,342,745 ÷ 2 = 180,171,372.5
If the quotient is a whole number, then 2 and 180,171,372.5 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 | 360,342,745 | |
| -1 | -360,342,745 |
Now, we try dividing 360,342,745 by 3:
360,342,745 ÷ 3 = 120,114,248.3333
If the quotient is a whole number, then 3 and 120,114,248.3333 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 | 360,342,745 | |
| -1 | -360,342,745 |
Let's try dividing by 4:
360,342,745 ÷ 4 = 90,085,686.25
If the quotient is a whole number, then 4 and 90,085,686.25 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 | 360,342,745 | |
| -1 | 360,342,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,249 | 6,245 | 8,243 | 8,743 | 41,215 | 43,715 | 57,701 | 288,505 | 10,295,507 | 51,477,535 | 72,068,549 | 360,342,745 |
| -1 | -5 | -7 | -35 | -1,249 | -6,245 | -8,243 | -8,743 | -41,215 | -43,715 | -57,701 | -288,505 | -10,295,507 | -51,477,535 | -72,068,549 | -360,342,745 |
