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 83,501,201, 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 | 83,501,201 | |
| -1 | -83,501,201 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 83,501,201.
Example:
1 x 83,501,201 = 83,501,201
and
-1 x -83,501,201 = 83,501,201
Notice both answers equal 83,501,201
With that explanation out of the way, let's continue. Next, we take the number 83,501,201 and divide it by 2:
83,501,201 ÷ 2 = 41,750,600.5
If the quotient is a whole number, then 2 and 41,750,600.5 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 | 83,501,201 | |
| -1 | -83,501,201 |
Now, we try dividing 83,501,201 by 3:
83,501,201 ÷ 3 = 27,833,733.6667
If the quotient is a whole number, then 3 and 27,833,733.6667 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 | 83,501,201 | |
| -1 | -83,501,201 |
Let's try dividing by 4:
83,501,201 ÷ 4 = 20,875,300.25
If the quotient is a whole number, then 4 and 20,875,300.25 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 | 83,501,201 | |
| -1 | 83,501,201 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 313 | 1,657 | 2,191 | 7,199 | 11,599 | 38,111 | 50,393 | 266,777 | 518,641 | 3,630,487 | 11,928,743 | 83,501,201 |
| -1 | -7 | -23 | -161 | -313 | -1,657 | -2,191 | -7,199 | -11,599 | -38,111 | -50,393 | -266,777 | -518,641 | -3,630,487 | -11,928,743 | -83,501,201 |
