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 265,410,475, 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 | 265,410,475 | |
| -1 | -265,410,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 265,410,475.
Example:
1 x 265,410,475 = 265,410,475
and
-1 x -265,410,475 = 265,410,475
Notice both answers equal 265,410,475
With that explanation out of the way, let's continue. Next, we take the number 265,410,475 and divide it by 2:
265,410,475 ÷ 2 = 132,705,237.5
If the quotient is a whole number, then 2 and 132,705,237.5 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 | 265,410,475 | |
| -1 | -265,410,475 |
Now, we try dividing 265,410,475 by 3:
265,410,475 ÷ 3 = 88,470,158.3333
If the quotient is a whole number, then 3 and 88,470,158.3333 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 | 265,410,475 | |
| -1 | -265,410,475 |
Let's try dividing by 4:
265,410,475 ÷ 4 = 66,352,618.75
If the quotient is a whole number, then 4 and 66,352,618.75 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 | 265,410,475 | |
| -1 | 265,410,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 121 | 275 | 605 | 3,025 | 87,739 | 438,695 | 965,129 | 2,193,475 | 4,825,645 | 10,616,419 | 24,128,225 | 53,082,095 | 265,410,475 |
| -1 | -5 | -11 | -25 | -55 | -121 | -275 | -605 | -3,025 | -87,739 | -438,695 | -965,129 | -2,193,475 | -4,825,645 | -10,616,419 | -24,128,225 | -53,082,095 | -265,410,475 |
