Find b from LCM

The least common multiple of 2,190 and b is 13,140. What is b?

Final Answer:

b =  13140

Step-by-step explanation:

a=2190 n=13140  x=n/a=13140/2190=6 y=a/x=2190/6=365  b=n=13140   Verifying Solution:   2190=2⋅3⋅5⋅73 13140=22⋅32⋅5⋅73 LCM(2190,13140)=22⋅32⋅5⋅73=13140  l=LCM(a,b)=LCM(2190,13140)=13140
