Luciano Horn · Answer 2

2,27 and 5

Step-by-step explanation:

lets find the prime factors of 270:

270=2*3*3*3*5*1,

the numbers 2,27, and 5 have LCM 270

the numbers 6,9, and 15 have LCM 270

the numbers 10 and 27 have LCM 270

etc,

just rearrange the prime factors, but include all of them in at least 2 numbers
