If in a certain code, 'ABCD' is written as 24 and 'EFGH' is written as 1680, then how is 'IJKL' written in that code?

Assign positional values: A=1, B=2, C=3, D=4. Product: 1×2×3×4 = 24. ✓ For E=5, F=6, G=7, H=8: Product = 5×6×7×8 = 1680. ✓ Pattern confirmed: multiply the positional values of each letter. For I=9, J=10, K=11, L=12: Product = 9×10×11×12 = 90×132 = 11880. So 'IJKL' is coded as 11880.
