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 652,721,615, 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 | 652,721,615 | |
| -1 | -652,721,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 652,721,615.
Example:
1 x 652,721,615 = 652,721,615
and
-1 x -652,721,615 = 652,721,615
Notice both answers equal 652,721,615
With that explanation out of the way, let's continue. Next, we take the number 652,721,615 and divide it by 2:
652,721,615 ÷ 2 = 326,360,807.5
If the quotient is a whole number, then 2 and 326,360,807.5 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 | 652,721,615 | |
| -1 | -652,721,615 |
Now, we try dividing 652,721,615 by 3:
652,721,615 ÷ 3 = 217,573,871.6667
If the quotient is a whole number, then 3 and 217,573,871.6667 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 | 652,721,615 | |
| -1 | -652,721,615 |
Let's try dividing by 4:
652,721,615 ÷ 4 = 163,180,403.75
If the quotient is a whole number, then 4 and 163,180,403.75 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 | 652,721,615 | |
| -1 | 652,721,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 1,434,553 | 7,172,765 | 10,041,871 | 18,649,189 | 50,209,355 | 93,245,945 | 130,544,323 | 652,721,615 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -1,434,553 | -7,172,765 | -10,041,871 | -18,649,189 | -50,209,355 | -93,245,945 | -130,544,323 | -652,721,615 |
