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 84,615,265, 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 | 84,615,265 | |
| -1 | -84,615,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 84,615,265.
Example:
1 x 84,615,265 = 84,615,265
and
-1 x -84,615,265 = 84,615,265
Notice both answers equal 84,615,265
With that explanation out of the way, let's continue. Next, we take the number 84,615,265 and divide it by 2:
84,615,265 ÷ 2 = 42,307,632.5
If the quotient is a whole number, then 2 and 42,307,632.5 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 | 84,615,265 | |
| -1 | -84,615,265 |
Now, we try dividing 84,615,265 by 3:
84,615,265 ÷ 3 = 28,205,088.3333
If the quotient is a whole number, then 3 and 28,205,088.3333 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 | 84,615,265 | |
| -1 | -84,615,265 |
Let's try dividing by 4:
84,615,265 ÷ 4 = 21,153,816.25
If the quotient is a whole number, then 4 and 21,153,816.25 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 | 84,615,265 | |
| -1 | 84,615,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 127,241 | 636,205 | 890,687 | 2,417,579 | 4,453,435 | 12,087,895 | 16,923,053 | 84,615,265 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -127,241 | -636,205 | -890,687 | -2,417,579 | -4,453,435 | -12,087,895 | -16,923,053 | -84,615,265 |
