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 652,471,883, 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 | 652,471,883 | |
| -1 | -652,471,883 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 652,471,883.
Example:
1 x 652,471,883 = 652,471,883
and
-1 x -652,471,883 = 652,471,883
Notice both answers equal 652,471,883
With that explanation out of the way, let's continue. Next, we take the number 652,471,883 and divide it by 2:
652,471,883 ÷ 2 = 326,235,941.5
If the quotient is a whole number, then 2 and 326,235,941.5 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 | 652,471,883 | |
| -1 | -652,471,883 |
Now, we try dividing 652,471,883 by 3:
652,471,883 ÷ 3 = 217,490,627.6667
If the quotient is a whole number, then 3 and 217,490,627.6667 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 | 652,471,883 | |
| -1 | -652,471,883 |
Let's try dividing by 4:
652,471,883 ÷ 4 = 163,117,970.75
If the quotient is a whole number, then 4 and 163,117,970.75 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 | 652,471,883 | |
| -1 | 652,471,883 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 73 | 119 | 511 | 1,241 | 8,687 | 75,109 | 525,763 | 1,276,853 | 5,482,957 | 8,937,971 | 38,380,699 | 93,210,269 | 652,471,883 |
| -1 | -7 | -17 | -73 | -119 | -511 | -1,241 | -8,687 | -75,109 | -525,763 | -1,276,853 | -5,482,957 | -8,937,971 | -38,380,699 | -93,210,269 | -652,471,883 |
