Find the lowest common multiple for 16 and 20
16= 2*2*2*2
20= 2*2*5
Then:
2*2*2*2*5=80
yes, 80
To find the lowest common multiple (LCM) of two numbers, you need to find the smallest number that is divisible by both of them.
First, let's list the multiples of each number:
Multiples of 16: 16, 32, 48, 64, 80, 96, 112, 128, 144, 160, ...
Multiples of 20: 20, 40, 60, 80, 100, 120, 140, 160, 180, 200, ...
Looking at the multiples, you can see that the first common multiple between 16 and 20 is 80. So, the LCM of 16 and 20 is 80.
