648
504
732
888

Answer 1

Option (1) is correct.

648 is the largest number that can be produced by multiplying any three individual numbers from the list.

Explanation:

Given number list, [-2, 1, 3, -8, 5, 9, -9, 4, 7, -7, 8]

We have to find the largest number that can be produced by multiplying any three individual numbers from the list.

For the largest number we have to choose the largest numbers from the list.

Since, 9 , -9 , 8 are the largest numbers in the list .

But since we need largest number, it has to be positive so we take two negative numbers and one positive that is -8 , 9 , -9 so the product will be positive.

• if two negative numbers are multiplied together, the product is always a positive number.

Thus, the product of -8 ,9 and -9 is

-9 × 9 = -81

and -81 × -8 = 648.

Hence from given options, option (1) is correct.

648 is the largest number that can be produced by multiplying any three individual numbers from the list.
