For this case we have that by definition, the LCM of two or more natural numbers is the smallest natural number that is a common multiple of all of them.
So:
A. 5 and 6
The LCM of 5 and 6 is the smallest positive integer that divides the numbers 5 and 6 without leaving a residue.
multiples:
5: 10,15,20,25,30,35,40,45
6: 12,18,24,30,36
[tex]LCM = 30[/tex]
B. 2 and 9
Multiplos:
2: 4,6,8,10,12,14,16,18
9: 18,27
[tex]LCM = 18[/tex]
C. 6 and 8
6: 12,18,24,30,36
8:16, 24
[tex]LCM = 24[/tex]
D. 2,5 and 6
Multiplos:
2: 4,6,8,10,12,14,16,18 ..., 30
5: 10,15,20,25,30,35,40,45
6: 12,18,24,30,36
[tex]LCM = 30[/tex]
Answer:
a.30
b.18
c.24
d.30
