Question

Find H.C.F and L.C.M of 42 and 144.

30 points and BRAINLIST FOR THE FIRST. ANSWER IN DETAIL.​

Answer 1

Step-by-step explanation:

Prime factorization of 42 = 2 * 3 * 7

Prime factorization of 144 = 2 * 2 * 2 * 2 * 3 * 3

LCM(42,144) = 2 * 2 * 2 * 2 * 3 * 3 * 7

                 = 1008

HCF(42,144) = 2 * 3

                 = 6

Hope it helps!

Answer 2

Step-by-step explanation:

(1)

HCF of 42, 144

42) 144 (3

     126

     ------

      18)42(2

           36

           ----

             6)18(3

                18

                ---

                 0

HCF of 42 and 144 = 6

(2)

Prime factorization of 42 = 2 * 3 * 7

Prime factorization of 144 = 2 * 2 * 2 * 2 * 3 * 3

LCM(42,144) = 2 * 2 * 2 * 2 * 3 * 3 * 7

                    = 1008
