Question 209585: Is the LCM of two numbers always divisible by the GCF of the two numbers? If so why. If not give an example

Given two numbers, the GCF is the lower power of common prime factors
.
and the LCM, is the greater power of common prime factors.
.
Since common factors are divided by common factors, division is possible
.
for example,,,,20,and 30
.
Prime factorization is,,,,2^2*5,,,2*3*5,,,respectively
.
GCF = 2*5=10
.
LCM = 2^2 *3*5 =60
.
LCM/GCF = 60/10 =6
.
