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 237,722,545, 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 | 237,722,545 | |
| -1 | -237,722,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 237,722,545.
Example:
1 x 237,722,545 = 237,722,545
and
-1 x -237,722,545 = 237,722,545
Notice both answers equal 237,722,545
With that explanation out of the way, let's continue. Next, we take the number 237,722,545 and divide it by 2:
237,722,545 ÷ 2 = 118,861,272.5
If the quotient is a whole number, then 2 and 118,861,272.5 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 | 237,722,545 | |
| -1 | -237,722,545 |
Now, we try dividing 237,722,545 by 3:
237,722,545 ÷ 3 = 79,240,848.3333
If the quotient is a whole number, then 3 and 79,240,848.3333 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 | 237,722,545 | |
| -1 | -237,722,545 |
Let's try dividing by 4:
237,722,545 ÷ 4 = 59,430,636.25
If the quotient is a whole number, then 4 and 59,430,636.25 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 | 237,722,545 | |
| -1 | 237,722,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 239 | 331 | 601 | 1,195 | 1,655 | 3,005 | 79,109 | 143,639 | 198,931 | 395,545 | 718,195 | 994,655 | 47,544,509 | 237,722,545 |
| -1 | -5 | -239 | -331 | -601 | -1,195 | -1,655 | -3,005 | -79,109 | -143,639 | -198,931 | -395,545 | -718,195 | -994,655 | -47,544,509 | -237,722,545 |
