Answer 1

Answer:

Factors of 360 - 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180

Multiples of 8 - .8, 16, 24 ,32 ,40, 48, 56, 64, 72, 80

Now we need to separate the numbers which are common and which exceed 50 - 72,90

⇒ 7-2 = 5

⇒ 9-0 = 9

The answer is 72
