A:
Positive:
1 x 100615977 x 143737113 x 77396991 x 110567
Negative:
-1 x -10061597-7 x -1437371-13 x -773969-91 x -110567
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 10,061,597, 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 | 10,061,597 | |
| -1 | -10,061,597 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,061,597.
Example:
1 x 10,061,597 = 10,061,597
and
-1 x -10,061,597 = 10,061,597
Notice both answers equal 10,061,597
With that explanation out of the way, let's continue. Next, we take the number 10,061,597 and divide it by 2:
10,061,597 ÷ 2 = 5,030,798.5
If the quotient is a whole number, then 2 and 5,030,798.5 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 | 10,061,597 | |
| -1 | -10,061,597 |
Now, we try dividing 10,061,597 by 3:
10,061,597 ÷ 3 = 3,353,865.6667
If the quotient is a whole number, then 3 and 3,353,865.6667 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 | 10,061,597 | |
| -1 | -10,061,597 |
Let's try dividing by 4:
10,061,597 ÷ 4 = 2,515,399.25
If the quotient is a whole number, then 4 and 2,515,399.25 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 | 10,061,597 | |
| -1 | 10,061,597 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 110,567 | 773,969 | 1,437,371 | 10,061,597 |
| -1 | -7 | -13 | -91 | -110,567 | -773,969 | -1,437,371 | -10,061,597 |
