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 705,025,265, 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 | 705,025,265 | |
| -1 | -705,025,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 705,025,265.
Example:
1 x 705,025,265 = 705,025,265
and
-1 x -705,025,265 = 705,025,265
Notice both answers equal 705,025,265
With that explanation out of the way, let's continue. Next, we take the number 705,025,265 and divide it by 2:
705,025,265 ÷ 2 = 352,512,632.5
If the quotient is a whole number, then 2 and 352,512,632.5 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 | 705,025,265 | |
| -1 | -705,025,265 |
Now, we try dividing 705,025,265 by 3:
705,025,265 ÷ 3 = 235,008,421.6667
If the quotient is a whole number, then 3 and 235,008,421.6667 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 | 705,025,265 | |
| -1 | -705,025,265 |
Let's try dividing by 4:
705,025,265 ÷ 4 = 176,256,316.25
If the quotient is a whole number, then 4 and 176,256,316.25 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 | 705,025,265 | |
| -1 | 705,025,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 3,709 | 5,431 | 18,545 | 25,963 | 27,155 | 38,017 | 129,815 | 190,085 | 20,143,579 | 100,717,895 | 141,005,053 | 705,025,265 |
| -1 | -5 | -7 | -35 | -3,709 | -5,431 | -18,545 | -25,963 | -27,155 | -38,017 | -129,815 | -190,085 | -20,143,579 | -100,717,895 | -141,005,053 | -705,025,265 |
