9 & 15
75 is LCM The numbers are 15 and 25 15 + 25 = 40 25 - 15 = 10 75 / 15 = 5 75 / 25 = 3
12 and 15 have a sum of 27 and a difference of 3. Their LCM is 60.

To find two numbers whose product is 90 and least common multiple (LCM) is 30, we need to consider the prime factorization of both numbers. The prime factors of 90 are 2 x 3 x 3 x 5, and the prime factors of 30 are 2 x 3 x 5. To find the numbers, we pair up the common factors and multiply them together, which gives us 2 x 3 = 6 and 5. Therefore, the two numbers are 6 and 15.
The GCF of 9 and 15 is 3. The LCM is 45.

When the numbers are co-prime, ie have no common factor. Simplest example is 2 & 3 whose LCM is 6
You need at least two numbers to find an LCM. If that's 5 and 3, the LCM is 15.
