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 700,187,435, 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 | 700,187,435 | |
| -1 | -700,187,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 700,187,435.
Example:
1 x 700,187,435 = 700,187,435
and
-1 x -700,187,435 = 700,187,435
Notice both answers equal 700,187,435
With that explanation out of the way, let's continue. Next, we take the number 700,187,435 and divide it by 2:
700,187,435 ÷ 2 = 350,093,717.5
If the quotient is a whole number, then 2 and 350,093,717.5 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 | 700,187,435 | |
| -1 | -700,187,435 |
Now, we try dividing 700,187,435 by 3:
700,187,435 ÷ 3 = 233,395,811.6667
If the quotient is a whole number, then 3 and 233,395,811.6667 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 | 700,187,435 | |
| -1 | -700,187,435 |
Let's try dividing by 4:
700,187,435 ÷ 4 = 175,046,858.75
If the quotient is a whole number, then 4 and 175,046,858.75 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 | 700,187,435 | |
| -1 | 700,187,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 235 | 1,091 | 2,731 | 5,455 | 13,655 | 51,277 | 128,357 | 256,385 | 641,785 | 2,979,521 | 14,897,605 | 140,037,487 | 700,187,435 |
| -1 | -5 | -47 | -235 | -1,091 | -2,731 | -5,455 | -13,655 | -51,277 | -128,357 | -256,385 | -641,785 | -2,979,521 | -14,897,605 | -140,037,487 | -700,187,435 |
