Answer 1

Answer:

The lcm is 25,680.

The hcf is 240.

Answer 2

H.C.F and L.C. M of 256 , 80 are 16 and 1280

Step-by-step explanation:

• Given number are 256 and 80

        Prime factorisation of given above number are

• 256 = 2×2×2×2×2×2×2×2

• 80   = 2×2×2×2×5

• H.C.F are multiplication of common number of prime factorisation of given number

        So

        H.C.F = 2×2×2×2 = 16

• L.C.M are multiplication of all prime factorisation of given number, but common number are written only one time.

        So

        L.C.M = 2×2×2×2×2×2×2×2×5 = 1280
