4 l 12, 20 l 3, 5 4*3*5 = 60 15 l 45, 60 3, 4 15*3*4 = 180 LCM = 180
The answer is 60. The way I approached this is: LCM of 3 and 6 is 6 (since 3 x 2 = 6 and 6 x 1 = 6), so you can disregard the 3. LCM of 4 and 6 is 12 ( 6 = 3 x 2 & 4 = 2 x 2) they have a common factor of 2, so 12 = 3 x 2 x 2. So now you have to figure LCM of 5 and 12. 5 and 12 only have a common factor of 1, so LCM of 5 & 12 is 5 times 12 = 60.
the LCM for 3,4, and 5 is 60 correct
For 7, 5, 4, 3, 2 the LCM is: 420
