Answer:
What is HCF and LCM of 12 and 18? HCF = 2 x 3 = 6 There is only one 2 in 18 and only one 3 in 12. LCM = 2 x 2 x 3 x 3 = 36 You need two 2's and two 3's to “cover” both 12 and 18. If the LCM is 18, HCF is 9, and one of the numbers is 101, what is the other number?

Answer:
6
Step-by-step explanation:
LCM of 12 and 18 = 2×2×3×3 [prime factorization]
= 36
factors of 12 = 1,2,3,4,6,12
factors of 18 = 1,2,3,6,9,18
factors of both 12 and 18 = 1,2,3,6
HCF of 12 and 18 = 6
LCM ÷ HCF
≈ 36 ÷ 6
= 6
