Answer:

63

Step-by-step explanation:

It leaves a remainder of 3 and given the number is the same

or,  a = 12a + 3

     a = 15b + 3

     a = 20c + 3

or, a-3 = 12a = 15b = 20c,

this means that "a-3" is actually the L.C.M of 12, 15, 20

12 = 2×2×3 = 2²×3

15 = 3×5

20 = 2×2×5 = 2²×5     or, L.C.M = 2²×3×5= 60

or, "a-3" = 60        or, a= 60+3 = 63

thus, 63 is the least number which when divided by 12, 15, 20 leaves remainder of 3.
