Question

Help me plz I dont know what it is

Answer 1

You have to pull apart 16 and 28 so you have their end prime factors
Which are:

16: 2 2 2 2
28: 2 7 2

If the same factor occurs more than once in both numbers, you multiply the factor with the greatest number of times it occurs multiply them to 7 to get the lcm with prime factorisation

2x2x2x2x7 =112
❤️❤️ if this doesn’t make sense message me I really don’t mind

Answer 2

The lease common denominator using prime factorization would be 2. 2 is the number they can both be divided by and is also a prime number
