When calculating the LCM of a set of numbers, firstly express each number as a product of its prime factors.

29 = 29 (it is a Prime number)

145 = 5 x 29

The LCM is the product of the highest power of each prime factor which gives us 5 & 29. (Note : In this example we do not have powers such as 5³ or 29²)

The Lowest (or Least)Common Multiple is therefore 5 x 29 = 145
