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 237,792,025, 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 | 237,792,025 | |
| -1 | -237,792,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 237,792,025.
Example:
1 x 237,792,025 = 237,792,025
and
-1 x -237,792,025 = 237,792,025
Notice both answers equal 237,792,025
With that explanation out of the way, let's continue. Next, we take the number 237,792,025 and divide it by 2:
237,792,025 ÷ 2 = 118,896,012.5
If the quotient is a whole number, then 2 and 118,896,012.5 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 | 237,792,025 | |
| -1 | -237,792,025 |
Now, we try dividing 237,792,025 by 3:
237,792,025 ÷ 3 = 79,264,008.3333
If the quotient is a whole number, then 3 and 79,264,008.3333 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 | 237,792,025 | |
| -1 | -237,792,025 |
Let's try dividing by 4:
237,792,025 ÷ 4 = 59,448,006.25
If the quotient is a whole number, then 4 and 59,448,006.25 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 | 237,792,025 | |
| -1 | 237,792,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 29 | 73 | 145 | 365 | 725 | 1,825 | 2,117 | 4,493 | 10,585 | 22,465 | 52,925 | 112,325 | 130,297 | 327,989 | 651,485 | 1,639,945 | 3,257,425 | 8,199,725 | 9,511,681 | 47,558,405 | 237,792,025 |
| -1 | -5 | -25 | -29 | -73 | -145 | -365 | -725 | -1,825 | -2,117 | -4,493 | -10,585 | -22,465 | -52,925 | -112,325 | -130,297 | -327,989 | -651,485 | -1,639,945 | -3,257,425 | -8,199,725 | -9,511,681 | -47,558,405 | -237,792,025 |
