Don’t know how to express my gratitude, u just earned a new sub

One method you could use to find LCM's is to put all the factors into a venn diagram, with the factors present in both numbers in the overlap. To find the LCM, you multiply all the numbers in the venn diagram (not the same as multiplying the original numbers together because if 2 is a factor in both, it only appears once in the overlap.) To find the HCF, you multiply the numbers in the overlap.
