Step-by-step explanation:

The prime factorization of 36 is: 2 x 2 x 3 x 3. The prime factorization of 40 is: 2 x 2 x 2 x 5. Eliminate the duplicate factors of the two lists, then multiply them once with the remaining factors of the lists to get lcm(36,36) = 360.

Answer:

LCM  = 720

Step-by-step explanation:

40 = 2 x 2 x 2 x 2 x 5                                             36 = 2 x 2 x 2 x 3 x 3

 2    40                                                                 2    36

 2    20                                                                 2     18

 2    10                                                                  2      9

 2     5                                                                   3     3

 5      1                                                                   3     1

40 = 2 x 2 x 2 x 2 x 5

36 = 2 x 2 x 2 x 3 x 3

LCM = 2 x 2 x 2 x 2 x 3 x 3 x 5

        = 720
