Question

6.Find the product of 378 and
46*​

Answer 1

Prime factors of 378 = 2 × 3 × 3 × 3 × 7 Prime factors of 180 = 2 × 2 × 3 × 3 × 5 Prime factors of 420 = 2 × 2 × 3 × 5 × 7 So, HCF of 378, 180 and 420 is 2 × 3 = 6 And LCM of 378, 180 and 420 is 2 × 2 × 3 × 3 × 3 × 5 × 7 = 3780 So, let us check whether LCM (378, 180 and 420) × HCF (378, 180 and 420) is equal to the product of the three numbers 3780 × 6 = 378 × 180 × 420 22680 ≠ 28576800 Hence LCM*HCF is not equal to the product of the three numbers.
