Answer 1

Answer:

The HCF is 30 and LCM is 600

Step-by-step explanation:

Numbers : 120 and 90

HCF:

2 | 120 2 | 90

2 | 60 5 | 45

2 | 30 3 | 9

5 | 15 3 | 3

3 | 3 | 1

| 1

\begin{gathered}120 = 2 \times 2 \times 2 \times 5 \times 3\\90 = 2 \times 3 \times 3 \times 5 \\HCF = 2 \times 3 \times 5\\HCF = 30\end{gathered}

120=2×2×2×5×3

90=2×3×3×5

HCF=2×3×5

HCF=30

LCM :

2 | 120 , 90

2 | 60 , 45

2 | 30 , 45

3 | 15 , 45

5 | 5 , 15

3 | 1 , 3

| 1 ,1

LCM =2 \times 2 \times 2 \times 3 \times 5 \times 5 = 6002×2×2×3×5×5=600

Hence The HCF is 30 and LCM is 600
