By applying Euclid’s division lemma5y = 32 × 1 + 22Since remainder ≠ 0, apply division lemma on division of 32 and remainder 22.32 = 22 × 1 + 10Since remainder ≠ 0, apply division lemma on division of 22 and remainder 10.22 = 10 × 2 + 2Since remainder ≠ 0, apply division lemma on division of 10 and remainder 2.10 = 2 × 5 [remainder 0]Hence, HCF of 32 and 54 10 2
