Webd0 = hcf hcf(a;b);hcf(a;c) and d = hcf(a;b;c). Then d divides both hcf(a;b) and hcf(a;c) by [1, Proposition 10.4]. Hence djd0 by [1, Proposition 10.4]. But d0 divides hcf(a;b) and hcf(a;c) by de nition of hcf. Then d0 divides a, b, and c, which implies that d0 6 d; because d the largest positive integer that divides a, b, and c. But djd0. Then ... WebApr 7, 2016 · I'm having trouble completing a proof that for positive integers a and b, that the least common multiple of a and b is ab/gcd (a,b).This is how I've approached it so far: For s = lcm (a,b) we have the following definition: i) a s and b s …
