15, 20 gives a remainder of 3 every time.​

Answer 1

Answer:

mark me has branilist..

Step-by-step explanation:

Prime factorizations first.12 = 2 x 2 x 3

15 = 3 x 5

18 = 2 x 3 x 3

27 = 3 x 3 x 3

LCM = 2 x 2 x 3 x 3 x 3 x 5 = 540

Since all of the remainders are 4 less than the divisors, the number will be 540 - 4 = 536

thank you so much..
