## Elementary Algebra

The prime factored form of 24 is: $24=2\times2\times2\times3$ The prime factored form of 54 is: $54=2\times3\times3\times3$ The prime factored form of 72 is: $72=2\times2\times2\times3\times3$ Since one 2 and one 3 is common to all three numbers, the greatest common factor of 24, 54 and 72 is $2\times3=6$. Therefore, the question statement is false.
