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
