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 83,272,673, 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 | 83,272,673 | |
| -1 | -83,272,673 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 83,272,673.
Example:
1 x 83,272,673 = 83,272,673
and
-1 x -83,272,673 = 83,272,673
Notice both answers equal 83,272,673
With that explanation out of the way, let's continue. Next, we take the number 83,272,673 and divide it by 2:
83,272,673 ÷ 2 = 41,636,336.5
If the quotient is a whole number, then 2 and 41,636,336.5 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 | 83,272,673 | |
| -1 | -83,272,673 |
Now, we try dividing 83,272,673 by 3:
83,272,673 ÷ 3 = 27,757,557.6667
If the quotient is a whole number, then 3 and 27,757,557.6667 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 | 83,272,673 | |
| -1 | -83,272,673 |
Let's try dividing by 4:
83,272,673 ÷ 4 = 20,818,168.25
If the quotient is a whole number, then 4 and 20,818,168.25 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 | 83,272,673 | |
| -1 | 83,272,673 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 47 | 149 | 253 | 517 | 1,081 | 1,639 | 2,209 | 3,427 | 7,003 | 11,891 | 24,299 | 37,697 | 50,807 | 77,033 | 161,069 | 329,141 | 558,877 | 1,771,759 | 3,620,551 | 7,570,243 | 83,272,673 |
| -1 | -11 | -23 | -47 | -149 | -253 | -517 | -1,081 | -1,639 | -2,209 | -3,427 | -7,003 | -11,891 | -24,299 | -37,697 | -50,807 | -77,033 | -161,069 | -329,141 | -558,877 | -1,771,759 | -3,620,551 | -7,570,243 | -83,272,673 |
