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 700,524,643, 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 | 700,524,643 | |
| -1 | -700,524,643 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 700,524,643.
Example:
1 x 700,524,643 = 700,524,643
and
-1 x -700,524,643 = 700,524,643
Notice both answers equal 700,524,643
With that explanation out of the way, let's continue. Next, we take the number 700,524,643 and divide it by 2:
700,524,643 ÷ 2 = 350,262,321.5
If the quotient is a whole number, then 2 and 350,262,321.5 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 | 700,524,643 | |
| -1 | -700,524,643 |
Now, we try dividing 700,524,643 by 3:
700,524,643 ÷ 3 = 233,508,214.3333
If the quotient is a whole number, then 3 and 233,508,214.3333 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 | 700,524,643 | |
| -1 | -700,524,643 |
Let's try dividing by 4:
700,524,643 ÷ 4 = 175,131,160.75
If the quotient is a whole number, then 4 and 175,131,160.75 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 | 700,524,643 | |
| -1 | 700,524,643 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 499 | 3,493 | 6,487 | 15,427 | 45,409 | 107,989 | 200,551 | 1,403,857 | 7,698,073 | 53,886,511 | 100,074,949 | 700,524,643 |
| -1 | -7 | -13 | -91 | -499 | -3,493 | -6,487 | -15,427 | -45,409 | -107,989 | -200,551 | -1,403,857 | -7,698,073 | -53,886,511 | -100,074,949 | -700,524,643 |
