I2.4 If the least common multiple (L.C.M.) of 76 and $d$ is 456 and the highest common factor (H.C.F.) of 76 and $d$ is $c$, determine the value of the positive integer $d$.
If the least common multiples (L.C.M.) of 76 and $d$ is 456 and the highest common factor (H.C.F.) of 76 and $d$ is $c$, determine the value of the positive integer $d$.
\[\begin{array}{l}76 \times d=\text { L.C.M. } \times \text { H.C.F. }=456 \times 4 \\ d=24\end{array}\]
