Question

7. Find the HCF and LCM of the following positive
integers by applying the prime factorisation
method:
(1) 24, 36, 176 (ii) 84,90, 120 (iii) 112, 144, 168.​

Answer 1

Step-by-step explanation:

(i) 24 = 2^3 × 3

36 = 2^2 ×3^2

176 = 2^4 × 11

HCF= 2^2 ×3=12

LCM=2^4×3^2×11

=1584

(ii) 84=2^2×3×7

90=2×3^2×5

120=2^3×3×5

HCF=2×3=6

LCM=2^3 × 3^2 × 5 × 7

=2520
