What is the greatest number which can exactly divide 192, 1056 and 1584?

48

The greatest number that exactly divide 192, 1056 and 1584 is HCF of these numbers.

So, *HCF = Value of 1 Ratio.* (The best way to find the HCF of numbers)

Therefore, ratio of numbers is

⇒ 192 : 1056 : 1584           

⇒ 48 : 264 : 396              (cut by 4)

⇒ 4 : 22 : 33                   ( cut by 12)

So value of 1 ratio = 12 × 4 = 48 = HCF
