What is the lowest common multiple of 3 and 4

So an example

least common multipule is like what is the smallest number both will fit into

example, 6 and 10, least common multilule is 30 because 6*5=30 and 3*10=30

so 3 and 4

factor each

3=3

4=2*2

so we have to have 2*2*3 which is 12

12 is least common multiplule
