Q. Which integer is the highest common factor of four positive integers A, B, C, and D?(1) A= 27, B=49.

A fraction will terminate if its denominator has no prime factor other than 2 or 5.
17/160Prime factors of "160" are "2" and "5". So, this fraction WILL terminate.
13/480One of the prime factors of "480" is "3".So, this will NOT terminate.
