Lesson Plan of Finding H CF of Three Numbers, up to 2 digits, Using Division Method Mathematics Grade V Students’ learning Outcomes ·          Find H CF of three numbers, up to 2 digits, using division method. Information for Teacher ·          There are many methods of finding H CF of two or more numbers, e.g. through prime factorization or through division etc. ·          If large numbers are given then it is hard to find all the common prime factors, in such situation, the H CF of these numbers can be found by using division. ·          There are two methods of division to find H CF, one by continuous division process and second is ladder method ·          In continuous division process, from two given numbers, any one is taken as divisor and other is as dividend, and after division, now remainder is taken as divisor and the first divisor is taken as dividend and we repeat division process. The process keep continue until we get the remainder ‘0’ hence

Lesson Plan of H CF up to 2 digits using Prime Factorization Method Mathematics Grade V Students’ Learning Outcomes ·          Find HCF of three numbers, up to 2 digits, using prime factorization method. Information for Teacher ·          H.C.F.: The highest common factors (H.C.F.) of two or more given numbers are the greatest which divides each of given numbers exactly. ·          Factorization means to express a number as the product of its factors. These factors are either composite numbers or prime numbers. (Except that 0 and 1 are neither prime nor composite). ·          Prime factorization means to express a number as the product of its prime factors.   E.g. 12 = 2x 2 x 3 o    Factors shared by two or more numbers are called common factors. E. g. o    Because ‘2’ is common in factors of both of these numbers so it is called common factor. o    The product of two or more common prime factors is the greatest number/factor, which is called Grea
