Prime Eliminations (Factorization, HCF, LCF)

This activity is an extension of the Prime formations activity. In this the learners will learners will make rectangle formations of a given number, with one of the sides fixed. Let us say they start with a fixed side of 2 and they were able to make a formation. They will then eliminate all but one column and repeat the process. They will do this until all the factors of a number are identified. They will these factors and identify HCF and LCF for a given set of numbers. ​
