60 and its multiples
lcm(2, 3, 5) = 30 → 2 digit common multiples are 30, 60, 90.
2 and 5 are the prime factors that are common to all multiples of 10.
20 pinkgal333:20, 40, 60 are all common multiples.
Both 2 and 5 are prime numbers so their product 2 x 5 = 10 is the Lowest (or Least) Common Multiple. The common multiples of 2 and 5 are therefore any number which is a multiple of 10.
