Answer 1

Answer:

LCM=5 & HCF=30

Step-by-step explanation:

10=2×5

15=3×5

LCM=5

HCF=2×3×5=30

Answer 2

Answer:

LCM = 30   HCF = 5

Step-by-step explanation:

LCM = 5 | 10, 15

        = 2 | 2, 3

        = 3 | 1, 3

         =   | 1, 1

5 x 2 x 3 = 30

HCF = 5 | 10                            5 | 15

       =  2 | 2                              3 | 3

        =   | 1                                   | 1
