HEY MATE THIS IS UR ANSWER....HOPE IT HELPS.....PLZ MARK ME AS BRAINLIEST.....PLZZZZZZZZ..

Step-by-step explanation:

90 = 3 x 3 x 2 x 5. H.C.F( 90, 144) = 2 x 3 x 3 = 18. L.C.M( 90, 144) = 2 x 2 x 2 x 2 x 3 x 3 x 5 = 720. We need to find the “Highest Common factor” (HCF) and “Least Common Multiple” (LCM) of 90 and 144 by using prime factorization method.
