First express each of the numbers in prime factors:
16 = 24
11 = 11 (Prime number)
20 = 22 x 5
Now, select the highest power for all prime numbers:
24, 11, and 5 then multiply them all together. (16)(11)(5) = 880 is the LCM
Note: 22 is not "counted" because it was a factor at a higher power in one of the other numbers. Take only the factor with the highest power.
The LCM of these three numbers is 80.
The least common multiple of the numbers 20, 16 and 24 is 240.
The least common multiple of the numbers 8, 20, 16 and 100 is 400.
LCM(16, 20) = 80
LCM of 11 and 20 is 220.
LCM of 8 16 20 is 80.
400 is the LCM. 8 x 50 = 400 20 x 20 = 400 16 x 25 = 400 100 x 4 = 400
The LCM is 400.
The gcf of 16 and 20 is 4. The lcm of 16 and 20 is 80
LCM of 8, 16, 20 = 80
The LCM of 14, 16, 20 is 560.
LCM of 16, 5, and 20 = 80
