WebSep 29, 2024 · The greatest element of L is 105 since a 105 for all a ∈ L. To find the greatest lower bound of 15 and 35, we first consider all elements g of L such that g ∣ 15. They are 1, 3, 5, and 15. The elements for which g ∣ 35 are 1, 5, 7, and 35. From these two lists, we see that ℓ = 5 and ℓ = 1 satisfy the required conditions.
