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 265,572,725, 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 | 265,572,725 | |
| -1 | -265,572,725 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 265,572,725.
Example:
1 x 265,572,725 = 265,572,725
and
-1 x -265,572,725 = 265,572,725
Notice both answers equal 265,572,725
With that explanation out of the way, let's continue. Next, we take the number 265,572,725 and divide it by 2:
265,572,725 ÷ 2 = 132,786,362.5
If the quotient is a whole number, then 2 and 132,786,362.5 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 | 265,572,725 | |
| -1 | -265,572,725 |
Now, we try dividing 265,572,725 by 3:
265,572,725 ÷ 3 = 88,524,241.6667
If the quotient is a whole number, then 3 and 88,524,241.6667 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 | 265,572,725 | |
| -1 | -265,572,725 |
Let's try dividing by 4:
265,572,725 ÷ 4 = 66,393,181.25
If the quotient is a whole number, then 4 and 66,393,181.25 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 | 265,572,725 | |
| -1 | 265,572,725 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 25 | 55 | 85 | 187 | 275 | 425 | 935 | 4,675 | 56,807 | 284,035 | 624,877 | 965,719 | 1,420,175 | 3,124,385 | 4,828,595 | 10,622,909 | 15,621,925 | 24,142,975 | 53,114,545 | 265,572,725 |
| -1 | -5 | -11 | -17 | -25 | -55 | -85 | -187 | -275 | -425 | -935 | -4,675 | -56,807 | -284,035 | -624,877 | -965,719 | -1,420,175 | -3,124,385 | -4,828,595 | -10,622,909 | -15,621,925 | -24,142,975 | -53,114,545 | -265,572,725 |
