8 is the highest common factor of 8 & 24. 8 * 1 = 8 and 8 * 3 = 24.
factors of 8: 1, 2, 4, 8 factors of 18: 1, 2, 3, 6, 9, 18 HCF: 2
hcf(16×27×49, 8×2725) = 8×27 = 216 Using prime factorisation: 16×27×49 = 2⁴ × 3³ × 7² 8×27×125 = 2³ × 3³ × 5³ → hcf = 2³ × 3³ = 8×27 = 216
The HCF of 144 and 192 is 48. The LCM is 576.
The HCF is 1
