Elp
given; 396 = 2² x 3² x 11
we see '2' has index 2. so it is short of one '2'
we see '3' has index 2. so it is short of one '3'
we see '11' has index 1. so it is short of two '11's
∴ k = 2 x 3 x 11² = 726
2100h = 2² x 3 x 5² x 7 x h
compare with 396 = 2² x 3² x 11
2100 is short of a factor of 11
& a factor 3
so to make 2100h a multiple of 396,
h = 3x11 = 33
