288 = 2 × 2 × 2 × 2 × 2 × 3 × 3
360 = 2 × 2 × 2 × 3 × 3 × 5
384 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 3
so hcf is = 2 × 2 × 2 × 3 = 24
lcm = 288 × 15 × 384 = 1658880
288 = 2 × 2 × 2 × 2 × 2 × 3 × 3
360 = 2 × 2 × 2 × 3 × 3 × 5
384 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 3
so hcf is = 2 × 2 × 2 × 3 = 24
lcm = 288 × 15 × 384 = 1658880
