Question

P is the LCM of 2,4,6,8,10; Q is the LCM of 1,3,5,7,9 and L is the LCM of P and Q. Then, which of the following is true?

(a)L=21P
(b)L=4Q
(c)L=63P
(d)L=16P

[explain briefly]​

Answer 1

Answer:

21p

Step-by-step explanation:

P is the LCM of 2,4,6,8,10

P=3(8)(5)

Q is the LCM of 1,3,5,7,9

Q=5(7)(9)

L is the LCM of P, Q.

Therefore,

L=3(8)(5)21 or 5(7)(9)8, i.e., 21P or 8Q.
