Question

If H.C.F (a, b) = 1, then H.C.F (a + b, a - b) =​

Answer 1

$\large \orange{\underline{ \orange{\underline{\bold{\purple{\overbrace{\pink{ \underbrace{ |\:\:\:\: \rm{ \mathfrak{ \red{ \huge{answer}}} \:\:\:\:|} }}}}}}}}}$

Hence it can be concluded that for any integer 'a' and 'b' with H.C.F(a,b)= 1, the H.C.F. (a + b, a - b)will always be equal to either 1 or 2. Hence option (C)is correct.

$\rm{ \bold{\red{ \underline{ \pink{ \underline{ \overline{ \purple{ \overline{ \green{ \:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\: \:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:}}}}}}}}}}$

Answer 2

Answer:

the answer is none

Step-by-step explanation:

the answer is 1 because a and b are are consequetive numbers any consequence number's HCF is 1 . Suppose we take a=2 and b=4 what is the difference
