Given,
The numbers 16 and 20
To Find,
The LCM of the given numbers
Solution,
To find the LCM, we must divide the two numbers their prime factors.
If we divide sixteen by its prime factors, we get:
16 = 2×2×2×2
If we divide 20 by its prime factors, we get:
20 = 2×2×5
Next, we take the common factors as one, for example 2×2 is common between the two numbers. Then, we multiply it with the rest of the prime factors.
LCM of 16 and 20 = 2×2×2×2×5
On calculating the above equation, we get:
LCM of 16 and 20 = 80
Hence, the LCM of 16 and 20 is 80.
