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 700,741,877, 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 | 700,741,877 | |
| -1 | -700,741,877 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 700,741,877.
Example:
1 x 700,741,877 = 700,741,877
and
-1 x -700,741,877 = 700,741,877
Notice both answers equal 700,741,877
With that explanation out of the way, let's continue. Next, we take the number 700,741,877 and divide it by 2:
700,741,877 ÷ 2 = 350,370,938.5
If the quotient is a whole number, then 2 and 350,370,938.5 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 | 700,741,877 | |
| -1 | -700,741,877 |
Now, we try dividing 700,741,877 by 3:
700,741,877 ÷ 3 = 233,580,625.6667
If the quotient is a whole number, then 3 and 233,580,625.6667 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 | 700,741,877 | |
| -1 | -700,741,877 |
Let's try dividing by 4:
700,741,877 ÷ 4 = 175,185,469.25
If the quotient is a whole number, then 4 and 175,185,469.25 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 | 700,741,877 | |
| -1 | 700,741,877 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 319 | 389 | 4,279 | 5,647 | 11,281 | 62,117 | 124,091 | 163,763 | 1,801,393 | 2,196,683 | 24,163,513 | 63,703,807 | 700,741,877 |
| -1 | -11 | -29 | -319 | -389 | -4,279 | -5,647 | -11,281 | -62,117 | -124,091 | -163,763 | -1,801,393 | -2,196,683 | -24,163,513 | -63,703,807 | -700,741,877 |
