It looks like you've uploaded an image showing a matrix or series of numbers, and you're asking about the least common multiple (LCM) and highest common factor (HCF). However, the image itself seems to display two matrices, but not a typical setup for calculating LCM or HCF, which is usually applied to integers.

To proceed with clarity:

1. LCM and HCF are typically used for integers. Is your goal to calculate these values for the numbers in the matrix?
2. The matrices appear to be part of a matrix addition or subtraction problem rather than a number-theory problem. Is this a matrix problem, or are you asking for LCM/HCF of specific numbers?

If you're working on matrix operations, I can guide you through matrix addition or other operations.

Please let me know if you would like to focus on:

• Matrix operations (addition, subtraction).
• Calculating LCM/HCF for certain numbers from the matrices.

Feel free to clarify, and I'll assist you further!

Would you like more details, or do you have specific questions? Here are 5 related questions to explore further:

1. Do you need help understanding the properties of matrix addition?
2. How do we calculate LCM and HCF for multiple integers?
3. Can we apply LCM and HCF concepts to matrices or matrix elements?
4. Would you like to review matrix multiplication in relation to these operations?
5. What is the significance of LCM and HCF in algebraic contexts?

Tip: When working with matrices, always ensure the dimensions are compatible for the operations you're applying.
