Question 1 If š = 22 Ć 3š„, š = 22 Ć 3 Ć 5, š = 22 Ć 3 Ć 7 and LCM (š, š, š) = 3780, then š„ is equal to (A) 1 (B) 2 (C) 3 (D) 0Given š = 22 Ć 3š„, š = 22 Ć 3 Ć 5, š = 22 Ć 3 Ć 7 Finding LCM of a, b & c We take 3x since will include 3 from b and c (as long as x ā„ 1) Thus, LCM (š, š, š) = 22 Ć 3x Ć 5 Ć 7 Also, given that LCM (š, š, š) = 3780, Putting values 3780 = 22 Ć 3x Ć 5 Ć 7 3780 = 4 Ć 3x Ć 5 Ć 7 3780/(4 Ć 5 Ć 7) = 3x 3x = šššš/(š Ć š Ć š) 3x = 945/(5 Ć 7) 3x = 189/7 3x = 27 3x = 33 Thus, x = 3 So, correct answer is (c)
