Question

17. If a, b and c are positive integers, then
(a-b-c -a + b + c is always divisible by
(1) Only (a + b) (2) Only (b + c)
(3) 3(a - b)
(4) 3(a + b)(b + c)(a + c)​

Answer 1

Answer:

The given number is divisible by all the terms, therefore the most suitable option is 3(a+b)(b+c)(a+c)

Step-by-step explanation:

The given term sum is equal to zero

We know the fact zero is divisible by all the numbers , it is divisible by (a+b),

(b+c), 3(a-b), 3(a+b)(b+c)(a+c)
