If k, m, and t are positive integers and k/6+m/4=t/12 do t and 12 have a common factor greater than 1 ? (1) k is a multiple of 3. (2) m is a multiple of 3. To clear the fractions, multiple the given equation by 12: 12(k/6 + m/4) = 12/(t/12) 2k + 3m = t. The factors of 12 greater than 1 are 2,3,4,6,...
