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 71,017,675, 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 | 71,017,675 | |
| -1 | -71,017,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 71,017,675.
Example:
1 x 71,017,675 = 71,017,675
and
-1 x -71,017,675 = 71,017,675
Notice both answers equal 71,017,675
With that explanation out of the way, let's continue. Next, we take the number 71,017,675 and divide it by 2:
71,017,675 ÷ 2 = 35,508,837.5
If the quotient is a whole number, then 2 and 35,508,837.5 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 | 71,017,675 | |
| -1 | -71,017,675 |
Now, we try dividing 71,017,675 by 3:
71,017,675 ÷ 3 = 23,672,558.3333
If the quotient is a whole number, then 3 and 23,672,558.3333 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 | 71,017,675 | |
| -1 | -71,017,675 |
Let's try dividing by 4:
71,017,675 ÷ 4 = 17,754,418.75
If the quotient is a whole number, then 4 and 17,754,418.75 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 | 71,017,675 | |
| -1 | 71,017,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 113 | 115 | 565 | 575 | 1,093 | 2,599 | 2,825 | 5,465 | 12,995 | 25,139 | 27,325 | 64,975 | 123,509 | 125,695 | 617,545 | 628,475 | 2,840,707 | 3,087,725 | 14,203,535 | 71,017,675 |
| -1 | -5 | -23 | -25 | -113 | -115 | -565 | -575 | -1,093 | -2,599 | -2,825 | -5,465 | -12,995 | -25,139 | -27,325 | -64,975 | -123,509 | -125,695 | -617,545 | -628,475 | -2,840,707 | -3,087,725 | -14,203,535 | -71,017,675 |
