Question 1 - Page 120 Find the prime factorisations of the following numbers: 64, 104, 105, 243, 320, 141, 1728, 729, 1024, 1331, 1000.Prime factorization of 64 ∴ 64 = 2 × 2 × 2 × 2 × 2 × 2 = 26 Prime factorization of 104 ∴ 104 = 2 × 2 × 2 × 13 = 23 × 13 Prime factorization of 243 ∴ 243 = 3 × 3 × 3 × 3 × 3 = 35 Prime factorization of 105 ∴ 105 = 3 × 5 × 7 Prime factorization of 320 ∴ 320 = 2 × 2 × 2 × 2 × 2 × 2 × 5 = 26 × 5 Prime factorization of 1728 ∴ 1728 = 2 × 2 × 2 × 2 × 2 × 2 × 3 × 3 × 3 = 26 × 33 Prime factorization of 729 ∴ 729 = 3 × 3 × 3 × 3 × 3 × 3 = 36 Prime factorization of 1024 ∴ 1024 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 = 210 Prime factorization of 141 ∴ 141 = 3 × 47 Prime factorization of 1331 ∴ 1331 = 11 × 11 × 11 = 113 Prime factorization of 1000 ∴ 1000 = 2 × 2 × 2 × 5 × 5 × 5 = 23 × 53
