A:
Positive:
1 x 641526555 x 128305317 x 916466535 x 1832933
Negative:
-1 x -64152655-5 x -12830531-7 x -9164665-35 x -1832933
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 64,152,655, 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 | 64,152,655 | |
| -1 | -64,152,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,152,655.
Example:
1 x 64,152,655 = 64,152,655
and
-1 x -64,152,655 = 64,152,655
Notice both answers equal 64,152,655
With that explanation out of the way, let's continue. Next, we take the number 64,152,655 and divide it by 2:
64,152,655 ÷ 2 = 32,076,327.5
If the quotient is a whole number, then 2 and 32,076,327.5 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 | 64,152,655 | |
| -1 | -64,152,655 |
Now, we try dividing 64,152,655 by 3:
64,152,655 ÷ 3 = 21,384,218.3333
If the quotient is a whole number, then 3 and 21,384,218.3333 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 | 64,152,655 | |
| -1 | -64,152,655 |
Let's try dividing by 4:
64,152,655 ÷ 4 = 16,038,163.75
If the quotient is a whole number, then 4 and 16,038,163.75 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 | 64,152,655 | |
| -1 | 64,152,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,832,933 | 9,164,665 | 12,830,531 | 64,152,655 |
| -1 | -5 | -7 | -35 | -1,832,933 | -9,164,665 | -12,830,531 | -64,152,655 |
