Answer:

LCM is 360, HCF is 3.

Step-by-step explanation:

LCM:

2         24,15,36

2         12,15,18

2         6,15,9

3         3,15,9

3         1,5,3

5         1,5,1

          1,1,1

Therefore, LCM of 24, 15 and 36 is 2*2*2*3*3*5= 360

HCF:

2     24                         3       15                          2        36

2     12                          5       5                           2        18

2     6                                     1                            3        9

3     3                                                                   3        3

      1                                                                              1

24=2*2*2*3

15=3*5

36=2*2*3*3

Therefore, the HCF of 24, 15 and 36 is 3.

Answer:

First, find the prime factors of the given integers: 24, 15 and 36

For, 24 = 2 × 2 x 2 x 3

15 = 3 × 5  

36 = 2 × 2 × 3 × 3

Now, LCM of 24, 15 and 36 = 2 × 2 × 2 × 3 × 3 × 5  

∴ LCM (24, 15, 36) = 360

And, HCF (24, 15 and 36) = 3
