the least common multiple is the lowest number that 5 and 16 (or any other numbers) go into that equal. for example, the lowest common multiple (LCM) of 5, and 10, is 10. because that is the lowest number that 5 and 10 will go into. so the lowest common multiple of 5 and 16 = 80.
there are two ways to solve, one by counting by the number: for example
5: 5,10,15,20,25,30,35,40,45,50,55,60,65,70,75,80
16: 16,32,48,64,80
the lowest number that is the same in both of these is 80.
Second way to solve:
find the prime factors of both 5 and 16: For example
16
^
8 2
^
4 2
^
2 2
5:5
16:2x2x2x2
now count the most amount of prime numbers in both 5 and 16.
so there are 5's and 2's. So there is only one 5, and four 2's. now multiply 5 times four 2's.
so it would look like 5x2x2x2x2= (LCM)
5x2=10
10x2=20
20x2=40
40x2=80
See, there are four 2's and one 5.
Hope this helped!
It is: 80

The LCM of 11 and 16 is: 176. Because 11 is prime, the LCM of 11 and 16 is their product, which is 176.
Multiples of 6 = 6, 12, 18, 24, 30, 36, 42, 48, 54...
Multiples of 16 = 16, 32, 48, 64...
Therefore least common multiple is 48.
The Least Common Multiple of 8, 11, 16 is: 176
The least common multiple of 16 , 24 = 48
Their least common multiple is 16.
Least Common Multiple (LCM) for 16 24 is 48.
The Least Common Multiple of 16 and 84 is 336.
