Use one of the usual methods to get the least common multiple. To get additional multiples, multiply this least common multiple by 0, by 1, by 2, by 3, etc.
936. All numbers divisible by 12 and 13 are multiplies of the lowest common multiple of 12 and 13 which is 156. 999 ÷ 156 = 621/52 ⇒ greatest multiple of 156 not bigger than 999 is 6 x 156 = 936.

The LCM of 12 and 13 is 156.
Least common multiple of 5 and 12 and 13 is 780.
The Least Common Multiple (LCM) for 4 12 13 is 156.
If they have a Prime multiple in common, then they are not co-prime numbers.Hence no 2 multiples of 13 exists to satisfy this condition.
