Look at the digits 36, 42, 54, 28, 84 and 77:

To write out all numbers which have 6 & 7 as a factor


\begin{gathered} 36\text{ = 2, 3, 4, 6, 9, 12, 18, 36} \\ 42=\text{ 2, 3},\text{ 6, 7, 14, 21, 42 } \\ 54\text{ = 2, 3, 6, 9, 18, 27, 54} \\ 28\text{ = 2, 4, 7, 14, 28} \\ 77\text{ = 7, 11} \\ 84\text{ = 2, 3, 4, 6, 7, }12,\text{ 14, 21, 28, 42, } \end{gathered}

Therefore the numbers which records 6 & 7 as a factor are


42\text{ and 84}
