Answer:
46656
Step-by-step explanation:
Let the number= x
then as per question;
x/4= a² => x=4a²
x/27=b³ => x=27b³
4a²=27b³
a=3n, b=2m
4*(3n)²=27*(2m)³
4*9n²=27*8m³
n²=6m³ => minimum of m=6, n= 6²=36
=======
a=3n= 108
b=2m= 12
x=4a²= 4*108²= 46656
x=27b³= 27*12³= 46656
Answer: minimum number to satisfy the given condition is 46656
